I can't remember who it was though, and I just remember that it was a nice try, and although the wings looked cool, and head and neck were terrible. I really liked the idea though, so I spent an entire day cutting up apples in different ways to see if I could make it better. I also saw a video online where someone used apple seeds to make eyes () which was really awesome, so I tried to incorporate that in. I ended up with this method for making the apple swan, which I think really looks incredible, and we ended up putting them on display for some dinner guests we had that night.


Take any bottle of soda, and get it to freeze on command! This “super cool trick works with cans of soda as well. Some quick links to a few of the materials I used: [✓] Coke: [✓] Quaich (little silver dish from Scotland) : To date, I haven't seen any tutorials on exactly how to get this self-freezing coke effect, so I'm excited to release this video in response to thousands of viewer requests.

Glass bottles are not recommended, as the ice expands when freezing and can shatter the glass explosively. Use of video content is at own risk. Music By: (Remember The Dreams) Project Inspired By: The viral YouTube video: How to Chill A Coke In just a second!! () and the process of nucleation was inspired by Self-Freezing Coke - Crazy from Kong! . Project History & More Info: I knew water could be turned to instant ice (), but was amazed to see that soda could be supercooled as well. The anomaly of self freezing soda has been observed by many people, usually by accident. Some people put a soda in the freezer to chill it, but then forget about it. When they've remembered and gone to get it, it's liquid until they open it, leaving them puzzled. Some people have noticed the effect by leaving the soda outside in cold temperatures. There is a vending machine in Hong Kong that sells supercooled Coke bottles, and the instructions to trigger nucleation is the same as in this video, however they recommend taking a sip when the cap is on. I believe this is to increase the chances of impurities being introduced into the liquid, making nucleation more likely. From what I've seen, the results in this experiment form an even thicker slush than the vending machine in Hong Kong. To get this effect, I put 4 bottles of 500mL (16.9 oz) soda in a freezer set at -24ºC (-11ºF) between 3:15- 4:00 hours. The longer they are in, the more dramatic and solid the slushy freeze will be. However, anytime after 3:15 hours there is a chance of them freezing before you take them out. Every freezer will be a little different temperature, and I've noticed the location of your bottles in the freezer makes a dramatic difference on freeze times. For best results, choose one consistent location in your freezer, and play around with freeze times to see what works best for you. In my freezer, the middle of the center rack settles at -24ºC (-11ºF) and takes 3:15 to super chill 4 bottles. Remember that the longer the freezer door is open, the more cold air will escape, and it will make your freeze times take much longer because your freezer has to cool down again. I've also noticed that the more frozen items you have in your freezer, the faster your soda will chill. In contrast, the less items in your freezer, the longer your soda will take to cool. Bottom line is, use a consistent environment for your experiments, and you'll get consistent results! I also experimented with 2 litter bottles, and had great results between 4-5 hours. The whole bottle slushifies in an instant. I experimented with Gatorade, Fresca, Mexican Sprite, Rootbeer, Orange sodas, Coke, Diet Coke, in bottle form, as well as in cans. I had super cooled success with them all! The trick to getting the 3 second slush, is quickly releasing the pressure in the bottle and re-securing the cap, flipping the bottle upside down, and back upright again. This is because the forming ice crystals will be moved around the length of the bottle, and trigger nucleation for the rest of the soda. If you were to just take the cap off, ice will form, and it will slowly spread downward, but might take upwards of 2 minutes for the bottle to completely freeze. Removing the pressure very slowly from the bottle, can keep the soda liquified, and give you the choice opportunity to play with supercooled soda outside of the bottle.

Music by: Scott & Brendo ( Skyward - Instrumental) Project inspired by: This foundry is an original design, which comes after months of experimenting, and over 10 different prototypes. The functionality is founded on ideas I collected while searching the internet for foundry designs. Background: For as long as I can remember, I've been intrigued by the idea of melting metal and making things with it. The problem has always been that it was out of reach or required really expensive equipment. In this project I experimented with 10 different prototypes, to develop a reusable backyard foundry that melts aluminum soda cans easily and safely. I tested different refractory recipes, different containers, different setting for blowing air, and different types of makeshift crucibles. I tried various ratios of portland cement, sand, perlite, plaster of paris, water, and even kitty litter. For containers, I experimented with clay pots, plastic buckets, no container, cinderblocks, and a galvanized steel pail. I ended up favoring the galvanized steel pail, and a mix of 50% plaster of paris, and 50% play sand, by volume, which was inspired by a video by NightHawkInLight How to Make a Soup Can Forge Depending on where you get, or find, your materials the cost can range anywhere from $5-$25 per unit. With the materials I used, I was able to make 2 units for under $40 ($20 each). Even on the high end, this is probably one of the cheapest, reliable, backyard foundries that can be made. I used mine to melt soda cans, and extract the aluminum for future metal casting projects. All the soda cans came from a local recycling depot. I bought back 30 lbs from the depot to avoid having to drink gallons and gallons of soda. :) I stored the ingots in various forms, which you can see in the next video, and tried a cool technique for making a little sword by pouring liquid metal into a bucket of sand. I'm planning to make a project video on how to do that in the near future. Thanks for watching, and please share!! :)

This is not a free energy device, over unity device, or a claim to be the solution to the worlds energy crisis. This is a project I did to experiment with the electrolysis of water, and the resulting gasses collected. Music By: Kevin Macleod (Breakdown) Project Inspired By: Smack's Booster : Project History & More Info: The generator requires electricity to electrolyze H2O (water) into gas. The resulting mixed gas is sometimes referred to as Oxy-Hydrogen gas, which is 2 parts Hydrogen (H2) and 1 part Oxygen (O2). I typically hook this up to my car battery while the vehicle is running, so the alternator takes most of the load. On 12 volts I get about 1.5 liters/minute, but when I want to make the gas faster, I hook 2 car batteries in series for 24 volts, and this exponentially increases the gas production to over 5 liters per minute. Current draw seems to be around 20-50 amps depending on whether you use 12-24 volts. High current draws mean the electrolyte heats up, and if left too long the plastic can warp or melt causing structural failure. Some people ask why the plates aren't all electrically connected. The plates that aren't connected are called floater plates, or neutral plates. There is too much information to post about them here, so do a google search, or check out websites like for an in depth explanation of the theory. I used KOH as my electrolyte because research suggested it was the best. I haven't experimented with other electrolytes, but have heard that salt, sodium hydroxide, vinegar, etc could work, but will dirty and may corrode the plates. Potassium Hydroxide keeps the system clean, however, it is caustic, so be careful if you choose to use it. You can probably get away with about 2-4 teaspoons of KOH per 6 liters of water. This system produces an extremely powerful OxyHydrogen gas. When the gas is used, it simply turns back into water, and that's good for the environment. However I believe it takes more electric energy to produce the gas than is obtained from the gas. This device merely converts the energy from one form to another, with given losses. As long as you have enough electricity, the amount of water already in this system is enough to produce thousands and thousands of liters of fuel. Some people say this is the fuel of the future. Either way, it's a very powerful gas! If you need more information, or want to purchase build plans for this design, you can get them here:

The container I made, originally, was made of glass. I thought it was a neat idea, but when I told my dad about it, he suggested hikers would probably prefer something more lightweight. I think he was right. When I saw the idea for joining two bottle caps together, I knew it was the perfect solution. I modified the idea slightly by using a hotel key as a divider to create 2 separate compartments, and sealed everything together with a 2 part epoxy. Now two items can be stored inside without much risk of them mixing, or leaking. The container weighs a mere 0.5 oz, unscrews from both ends, and is completely waterproof. I've been really happy with this quick and easy project, and already made 5 of them to store items in my emergency kit. You'll see what I put inside mine in an upcoming project video :)

Here is how to light up an LED and power a calculator using some loose pocket change! I found this link that helps explain the reaction and why it works: Basically, a galvanic cell consists of at least two half cells, a reduction cell and an oxidation cell. Chemical reactions in the two half cells provide the electrons for the galvanic cell operations. Copper ions gain electrons (reduced) while zinc ions give them up (oxidized). = (redox) An electrolyte like salt water or vinegar helps get the metals into ions. Electrons flow through the electric conductors connecting the electrodes, as ions flow through the salt bridge. The overall reaction of the galvanic cell is: Zn + Cu2+ = Zn2+ + Cu

See What Else I’m Up To: Instagram: Facebook:  Music By: Music by Scott & Brendo “American Dream” Instrumental iTunes: YouTube: Project Inspired By: A moment of inspiration I had while working on the Exploding Cap Dart video () Project History & More Info: Do you remember the Exploding Cap Dart project? () While I was working on different prototypes for that exploding blowgun ammo, I got wondering about the cap-gun caps themselves, and how they exploded on impact. I spent a considerable amount of time on the internet researching, and trying to figure out what the composition of cap gun caps were. I was very curious to learn what composition could be stable enough to sit undisturbed, indefinitely, but explode suddenly and powerfully when hit with enough force. Armstrong's Mixture is highly volatile and extremely dangerous compound in large quantities, and has been known to explode just by stirring it too aggressively. However in small batches like cap-gun caps, it's exciting, and relatively harmless. I found a few websites, PDF's and online studies suggesting different ways to make improvised versions of the mixture using safety matches. This method doesn't create a pure composition though, and there really isn't any way to measure exact amounts. But in experimenting, I did figure out an easy way to make it work consistently, every time. At this point I have a fair amount of experience with Armstrong's Mixture, and some things you need to know about it are this; - Treat it like it could explode spontaneously at any moment, and make sure you have safety precautions in place. This way if it does, you'll be prepared for it. - Stick to very small batches, and treat it with caution and respect. Don't use more than 1 match-head. 2 at the most! This makes enough powder for 10 Thunder Caps, which are about 5-10 times more powerful than regular cap-gun caps in-and-of themselves. And while the powder from only 2 matches might not seem like much. trust me, you DON'T want it going off all at once. - If you mix it up too aggressively, it can go off unexpectedly, and can be extremely loud, leaving your ears ringing. It can also be set off with friction, impact, heat, and electrical sparks. Wear ear-plugs and safety glasses at all times. Saying all that, I've never actually had the composition go off unexpectedly, so long as I was being extremely gentle with it. I usually keep each movement as light as a feather and typically mix it with wooden sticks, razor blades, and anything else that is convenient and expendable, so far with 100% success. It's important to note that I always expect it to go off at any time, and am prepared in case it does. Attempts to get the mixture to go off while stirring aggressively were hit or miss. Most of the time nothing happened. However, every now and again, it would explode when it was least expected. I believe the “Thunder Caps” project to be a safe and enjoyable experience, so long as it's experimented with in very small quantities. However if you try this yourself, remember that any actions and reactions you produce are at your own risk, and you are responsible for the consequences.

Music By: TheFatRat - Licensed by Tasty Song Title: Xenogenesis Music Video: . Label Channel: Project Inspired By: An indirect suggestion my dad made for me to try and make something practical out of brass. He didn't expect I'd end up making these! Project History & More Info: The weather has cooled off quite a bit, which has turned my interest back to keeping warm by casting metal. This time round I wanted to play with higher temperature metals, like brass. So I made a trip to a local shooting range, and salvaged a whole bucket-load of spent brass casings. Quite a few people have asked whether my backyard foundry can melt brass, and I was curious myself, so I threw a few handfuls of casings into a crucible and fired them up. I tried using lump charcoal because it burns hotter and faster than briquettes, and a clay crucible purchased from the internet because it withstands heat better, and lasts longer than steel. I was impressed that the brass melted down without hesitation, and I was able to easily cast mini brass muffins the same day. A couple things worth mentioning are that the melting point of brass is around the boiling point of zinc. I noticed this in real-life when the metal started bubbling, and shooting out white flames. I wasn't sure what it was until I looked it up, but it was most likely zinc oxide fumes being released. Zinc Oxide can be toxic in large quantities, and although it's never happened to me, claims are that it can cause metal fume fever, which gives flu like symptoms. You should also know that brass is over 3 times heavier than aluminum, so expect the crucible to have a lot more weight to it, making it harder to handle. My dad was visiting at the time and confirmed my thoughts about it by suggesting I try making something more practical and useful. So I thought it would be fun to make some Brass Knuckle paperweights. I looked online at different varieties of brass knuckles, then drew my own version in photoshop, and used the Styro-Slicer and the lost-foam casting technique to make a rough pair of knuckles. I cast another pair the same way, and spent another 8 hours sanding and buffing them up to a mirror finish, then wondered how I could take them to the next level. Spikes seemed like a cool idea, inspired by a picture I saw on a google image search, so I stopped at an alternative clothing store and picked up a spiked choker collar, and repurposed the spikes for my piece of metal art. These are not designed or intended to be used as weapons. Possession of Brass Knuckles is illegal in most countries, (but not where I live), however I created these simply for artistic expression, and use them mainly as workshop décor. (paperweights).

Most people wouldn't think of butter as a flammable substance, but in this project they are! We're making emergency candles that burn for hours. using some toilet paper, and a bit of butter! Endcard Links: Emergency Power: Water Pump: Char Cloth: Stick Fire: See What Else I’m Up To: Instagram: Facebook:  Pinterest:  Business Inquiries: For business and sponsorship inquiries please contact us directly: WARNING: An open flame poses a fire hazard. Do not use near any flammable or explosive material. Use of this video content is at your own risk. Music By: Music by Jason Shaw (TU-ForeverBelieve) Project Inspired By: This was an original idea. I had been playing around with making candles with vegetable oil and was about to make a video on some ways to do that. One night an idea popped into my head about melted butter and I wondered if that would work. Project History & More Info: To make butter burn, we actually need to vaporize it first! A bit of rolled up toilet paper acts as a wick, and when pushed down into the center of a block of butter and ignited, we've may have created the worlds simplest candle. The butter below the wick begins to melt and soak up into the paper. The heat aids the liquid butter to be released as a vapor, and it's the vapor that's flammable. I used an 8oz block of butter and cut it in half. Each half burns for about 4 hours each, however, during the last 2 hours it seems most of the butter liquifies and your wick may need some support. I used a paperclip to give some stability. Another idea would be to cut the butter into 8 sections of 1oz each and make 8 candles! Each ounce should burn for about 1 hour.

The truth, with photons. I hope I've articulated everything clearly in this video. If not, I'll clarify in comments. Thanks to everyone who appears in this video and thanks to everyone who watches this video! Veritasium is of course a combination of the latin 'veritas' meaning truth, and the common element ending 'ium'. I guess this is my version of the 'draw my life' craze that rolled through YouTube many years ago. Except I wanted to tell my story with the actual moments, the photons, the stored magnetic states. There's something about that which is so important to me (because I think the alternative involves fooling yourself) which is why I'm so fascinated by film and video. One of my inspirations for the name Veritasium came from the end of the poem Ode on a Grecian Urn by John Keats, in which he writes: Beauty is truth, truth beauty,—that is all Ye know on earth, and all ye need to know.

Have fun, but use caution and common sense, and always remember that any experiment you try, is at your own risk. Music By: Jens Kiilstofte - “Morning Cruise” Project Inspired By: My dad. He's a huge fan of popcorn and I wanted a quick and easy way to make some when he came to visit. I took more inspiration from microwave popcorn, and the internet. I ripped bags of microwave popcorn apart to figure out how they worked, researched the internet for DIY ideas, and experimented on my own with 20-30 batches to get the results you see here. Project History & More Info: I wondered if there was a way to make a single bag of popcorn at home, that would be ready to eat right away. No buttering, no salting. just ready to eat as soon as it was popped. Of course I was inspired by microwave popcorn, because it can already do that. But some research suggests there may be harmful chemicals in the heat-resistant lining that are released when the kernels are cooked. I experimented by popping kernels in butter, but most of the time the butter burned, and either melted the plastic containers I was using, or scorched them. I experimented with coconut oil, and that worked really really well, but there wasn't much flavor and I wanted the recipe to use very common ingredients, so olive oil ended up being my preference. For containers, I experimented with plastic, glass, and even slurpee and coffee cups, but they all either warped, stained, or melted at the seams and fell apart once in a while. Not very reliable. After searching around the internet, I realized this actually isn't a very new idea, and people have been making microwave popcorn in brown paper bags for years. So I tried the brown paper bag method, and while it was a bit messy, it worked perfectly every time. I experimented with different recipes and amounts trying to get a single bag to pop and be ready to eat straight out of the microwave. This is the recipe I use now, after weeks of testing; 1/3 Cup Popcorn 1 Tsp Olive Oil ½ Tsp Salt I found that if the kernels were coated in the oil first, they would pop faster, and be more complete. I also found that throwing all the ingredients in at the same time will still season everything and yield a great taste. You could shake the bag to make the contents more uniform, but it still works either way! :) Just for fun, my wife suggested I try adding some sugar to see if it would make instant kettle corn. and it did! So: (optional) – Add 1 TBSP Sugar to make Kettle Korn Kettle Korn is a sweet and salty version of popcorn for people who like it like that. My personal preference however, is salty. So I usually leave the sugar out. I included the option in this video because many Americans are fans of the Kettle Korn taste. Enjoy! :)

Light a survival fire with your pee. If you're into survival skills and fire-making techniques, this is a great trick to know if urine trouble. Endcard Links: Fire With Water: Fire Piston: Solar Scorcher: Char Cloth: See What Else I’m Up To: Instagram: Facebook:  Pinterest:  Business Inquiries: For business and sponsorship inquiries please contact us directly: WARNING: Use of this video content is at your own risk. Music By: Kevin Macleod (Stormfront, Stomp Dance) Project Inspired By: Dual Survival - Urine Ignition Project History & More Info: This is a great trick to know if urine trouble. If clear liquids can be conformed to the shape of a sphere, sunlight can be refracted through the fluid and the energy can be focused to a point. Clear water is one of the best choices because it doesn't absorb any of the suns energy, so more heat is transferred to the tinder. Colored liquids, or liquids in colored bottles can still work, but energy is lost, and that could be the difference between getting tinder ignition or not. After making fires with various water bottles, and posting my first video on it in 2010, someone commented and said they saw a guy on Dual Survival do it with his urine. That sounded pretty amazing to me, so I looked up the link on YouTube and saw the clip. It seemed like he had quite a bit of trouble actually getting his fire going, and I thought that if I were ever in a survival situation like that, the last thing I would want to be doing is trying for hours how to figure out how it works. It's better to be prepared beforehand. This video comes after many experiments of playing with various techniques. I found that using plastic wrap and urine made a combination that gave great success, and within a minute or two I could have a flame! When done correctly, it works just the same as a magnifying glass. Practicing with the amount of pressure is key, because too little and you won't have a good lens. Too much, and the plastic bursts and you're soaking wet. FAQ's: Q: Why did I wrap an apple in plastic wrap? A: Of course the video is fictional, however the survival techniques portrayed are real. I wrapped my apple with plastic wrap because I've seen it done before at hotels, and I wanted to give an example of how random resources can be used as tools. If you don't wrap your apples in plastic wrap, perhaps you wrap your sandwich, or various other food items? The plastic baggie holding the celery can also be used in a very similar manner. Q: Why did I use a page from the map for tinder instead of grass or leaves? A: This liquid lens technique will light any tinder that could be lit with a magnifying glass, since that's what it is in essence. I used a piece of paper as an example because most people have access to that as a material they could practice with. I chose paper because it's easily duplicatable by anyone wanting to try. Q: Why does the urine change color just before I light the tinder? Did I cheat? A: The urine changes color mid video, and that's because when I went to re-set my camera for a different angled shot, I dropped the first sack of urine. Awkward to hold the sack, and adjust the camera on rocky terrain at the same time. I lost my urine and had to wait for another round. which, by that point was more hydrated because of all the water I'd drank earlier, and therefore more clear in color. In either case, I have the same success igniting tinder with either liquid lens so the difference made by the color is negligible.

Licensed under Creative Commons Attribution 4.0 International (.) Project Inspired By: This was an original idea (original to me anyway) Project History & More Info: 2 years ago, one of my brothers gave me a set of Star Wars ice cube trays. But rather than using them for ice cubes, I wanted to try something different. I typically make my own gummy recipe and make LEGO gummies with a custom mold I made a few years ago, but this time I got a bag full of gummy bears to make it even easier. I have always melted them on the stove, on low heat, but that was taking upwards of 10 minutes. So I randomly tried putting a batch in the microwave for a few seconds, and was amazed by the result. Just a few seconds in the microwave is all it takes to make a cup full of molten gummy syrup. I don't go longer than 15 seconds at a time because if you go too long, the syrup will start boiling and bubbling up out of the container, making a big sticky mess in the microwave. In some cases, 15 seconds is all it takes. But if that's not long enough to melt everything, try another 10-15 seconds. I recommend using a glass container for melting the gummies. Plastics could melt or warp. This idea could be adapted to make custom gummies of any shape and size. Enjoy! *Special thanks to Audible.com for sponsoring another one of my videos!

Can you find the mistakes? I am student , I am agree , Yesterday, I'm go downtown , He no have money , I want to meet the downtown. If you don't know, this is the lesson for you! These are mistakes made by students of all levels, so watch this video and learn to avoid these common errors. Take the quiz here: And don't forget to check out our other video on 5 common English learner mistakes: TRANSCRIPT Hey, everyone. I'm Alex. Thanks for clicking, and welcome to this lesson on five more common English learner mistakes. So if you have watched my other video on five common English learner mistakes, this is a follow up to give you five more. So let's not waste time and get right to it. Here we go with No. 1. So this first mistake is common because in many languages, when you discuss jobs or your station in life, you don't use articles even if you come from a country where there are articles in the language. So for example, I am student. He is engineer. If I ask you, What do you do , you need to use an article because student is countable; it's singular; and engineer' is countable and it's singular. So you have to say, I am a student. He is an engineer. Now, let's move on to No. 2. Okay. Here, we have two sentences on the board. We have, I am agree. Are you agree? So in this situation, agree is a verb. We don't say, I am agree. You can just say, I agree. If it's negative, I don't agree or, I disagree. And the question is not, Are you agree? It's, Do you agree? Now, if you are set on wanting to say I am and use agree in some way, you would have to say, I am in agreement. This is very formal, but it is possible. Otherwise, you say, I agree or, I disagree and, Do you agree? Now, let's move on to No. 3. This next mistake is about the use of the past tense. For new English speakers, because they can't form the past tense, sometimes they use the verb to be with the verb. So I have heard, I'm go downtown yesterday. Or, He was see his cousin. If you are speaking in the past, make sure you simply use the past simple verb. In this situation, we don't say I'm go. The past of go is went. I went downtown. We don't say he was see. The past of see is saw. So this is about using the past simple form of the verb to speak about the past. Never say I'm go , I'm do , I'm make. I saw ; I made ; I did ; I played. Okay? Now, let's move on to No. 4. Now, this mistake is about using negatives. In many languages, whether they're European or Latin, Spanish, I hear this frequently. So you might hear, He no have money or, They no like chocolate. So if you are making a sentence in the sent simple, and you want to make it negative, you have to use doesn't and don't. So not he no have but, He doesn't have. Okay? Not they no like chocolate but, They don't like chocolate. So make sure you learn how to make negative sentences. He doesn't ; I don't ; we don't ; they don't ; not he no , she no , I no. All right? Now, let's move on to No. 5. Finally, here we have a word choice error. And this is because maybe speakers translate from their own language, and many languages, you can use the verbs meet or know to talk about going to places and getting to know cities and towns, for example. So, I want to meet the city or, Yesterday, I knew downtown. Now, in English, we don't really use the verbs know and meet to talk about getting to know a place. You can use the verbs explore or get to know or visit. So you can say, you know, I want to explore the city. I want to go around the city. Yesterday, I knew downtown -- Yesterday, I traveled around downtown. And you can also use terms like get to know a place. You can visit a place. You can explore a place. Okay? But you can't meet a park. You can meet a person, but you can't meet a place. Now, let's review all five of these mistakes one more time. All right. So to review, No. 1, I am a student. If you want to talk about your status in life. Are you a student? An engineer? Are you a teacher? Etc. you need to use an article to talk about jobs, professions, talk about your station in life. No. 2, I agree, not I am agree. Do you agree? Not are you agree? No. 3, I went downtown. I saw my cousin. So remember, memorize those past tense verbs. Not I was go or I am go. I went ; I saw ; I did. All right?

How do you measure big forces accurately? By calibrating your force transducer on the world's biggest weight - 1,000,000 pounds of force. This machine ensures planes don't break apart, jets provide required thrust, and rockets make it to their destination. Thanks to the people at NIST for showing me around: Rick Seifarth and Ben Stein. Animations here are by Sean Kelley and additional footage by Jennifer Lauren Lee. Special thanks to Patreon Supporters: Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen Support Veritasium on Patreon: Before visiting NIST in Washington DC I had no idea machines like this existed. Surely there's an accurate way to measure forces without creating such a huge known force?! Nope. This appears to be the best way, with a stack of 20 x 50,000 lb masses creating a maximum force of 4.45 MN or 1,000,000 pounds of force. I also wouldn't have thought about all the corrections that need applying - for example buoyancy subtracts about 125 pounds from the weight of the stack. Plus the local gravitational field strength must be taken into account. And, the gravitational field varies below grade. All of this must be taken into account in order to limit uncertainty to just five parts per million (.0005%) Music from The Epidemic Sound Serene Story 2


*Watch with headphones on! Is 45 minutes really the longest anyone can stay in a perfectly silent, pitch-black room? Support Veritasium on Patreon Check out Audible: Want to watch the whole hour of silence? Many stories have circulated claiming the longest anyone has stayed in an ultra-quiet anechoic chamber is 45 minutes, the reason being any longer would drive you insane. To me this sounded like unsubstantiated rubbish, like the claim the Great Wall is the only manmade structure visible from space. So I put my own psyche on the line, subjecting myself to over an hour of the most intense quiet on Earth. No, this was not THE quietest room on Earth (-9dB) but it is one of the quietest, and the truth is once you put a person inside, they are by far the loudest thing in there so the sound rating of the room is irrelevant. I was not surprised to find that I could stay in there for as long as I liked and feel perfectly fine. What was surprising is that my heartbeat was audible. You can hear it on the sound recording. Now I wasn't consciously aware of the sound of my heart while in the room, but I was more aware of the feeling of it beating.
