Pouring Molten Aluminum In 'Spitballs' Causes A Cool Reaction

Backyard Scientists T-Shirts! Limited Edition campaign, buy one now! - I packed a fish tank completely full of water balls (water beads, water balz, orbeez, spitballs...). I'm guessing there are over 10,000 in there! Anyway, I melted a bunch of aluminum pipes, and once it became red hot, it was time to dump it in the fish tank. In the fish tank, the molten aluminum cooled down in an instant and made such a cool design, just as predicted. No two were alike! Check out all the different designs that were made in the video! Vat 19 was nice enough to supply me with the spitballs to use in this video :) Facebook: Instagram: Twitter: Website: Science is a cool subject to explore, but some of the experiments just aren't safe to do at your own home. That is why the Internet is filled with videos of both professionals and enthusiasts pushing the boundaries of safety as they demonstrate various science experiments, so you don't have to! Cue Kevin Kohler a.k.a. TheBackyardScientist! What would we do if it weren't for him? The guy has shown us how magnesium burns and whether you can put it out, he has even got on the fidget spinner craze train and showed us what a rocket powered fidget spinner looks like. These experiments of his were quite dangerous, so it is better to just open TheBackyardScientist channel here on and watch them from the safety of your own couch.

Learn How To Extinguish A Magnesium Fire4m50s

Learn How To Extinguish A Magnesium Fire

Magnesium is a pretty cool thing. It's the ninth most abundant element in the universe and fourth most common on our planet. The coolest thing about magnesium is that it can be used as an emergency fire starter because it has a low melting point. A magnesium fire burns bright and it's virtually inextinguishable, so don't try this next experiment at home! Chemistry is a fun subject, but you need to take a lot of precautions. The Backyard Scientist will take that burden off your shoulders by showing you how magnesium ignites, how bright magnesium fire is and how to extinguish it. He tries covering the fire with dry ice, which is basically frozen CO2, but the fire takes it's sweet time to go out, since magnesium fire draws the oxygen from the CO2. Don't try to put it out with water either! It will cause an explosion that looks really cool in slow-mo, but it may cause additional damage. The best way to put out a magnesium fire is to cover it in sand, in order to smother the fire by removing its O2 source! Are you a science junkie? Share this video with your friends to educate them on the effects and dangers of a magnesium fire.

This Is What Happens When You Pour Molten Salt In Watermelons5m38s

This Is What Happens When You Pour Molten Salt In Watermelons

If you have never heard of molten salt, well, this video might not make too much sense to you. But just think about it. We have melted sugar before and it gave us the tastiest thing ever - caramel. So why can’t we do it with salt too?! In this video by TheBackyardScientist, we are introduced to a whole new world of experiments. He gives us the answers to the most important question in the world - “What happens to a watermelon when you pour molten salt on it?” He starts the experiment by heating up plain ol’ kosher salt to the point of no return. Then, he drills a coconut and places it on a spinning rack. Slowly, but surely, he brings the molten salt can on top of the coconut and pours it in. And then, the unexplainable happens. The coconut explodes into tiny pieces, as if it was blasted with a C4. If that wasn’t enough, he decides to do a second round of this experiment, only this time, he uses a watermelon to do it. And the result? Oh, it’s much better than the first time. The sweet sugary goodness catapults all over his yard. Thankfully, it didn’t get to the neighbor’s yard, because we’re sure they wouldn’t be too happy about it.

How (Not) To Make A Rocket Powered Fidget Spinner4m45s

How (Not) To Make A Rocket Powered Fidget Spinner

In the crazy era of fidget spinners, TheBackyardScientist made a giant rocket-powered fidget spinner, so you won’t have to! Kevin Kohler a.k.a. TheBackyardScientist gives his own spin to the fidget spinner craze by custom building a giant fidget spinner out of metal and gave it an extra feature. The crazy backyard scientist added rockets to each of the fidget’s lobes, thus making it the ultra fidget spinner! He assembles his creation on a tripod and sets up a makeshift blast barrier, just in case. His girlfriend is already there, waiting to see what will happen. This video shows just why every one of these videos comes with a disclaimer “do not try this at home”. Just when the spinner reaches speeds of over 5.000 rpm, two of the rockets break free, shooting shrapnel all over the scientist’s backyard, almost hitting his girlfriend and definitely hitting his car! In case you were wondering what caused the dysfunction, physics has a simple answer to it - centrifugal force! The spinner was going so fast, that the gunpowder inside the rocket “engines” was being forced out the back and to the sides of the rockets, causing a magnificent shower of sparks! So there you have it. You can make a self-propelled fidget spinner, but it is not without consequences. Definitely don’t try this at home!

Pouring Molten Aluminum Into A Pool4m26s

Pouring Molten Aluminum Into A Pool

Kevin Kohler, the Backyard Scientist is back at it again with a new video featuring one of his favorite molten aluminum. It is good that Kevin takes on these complex and potentially extremely dangerous experiments on himself, because he has the cool gadgets and cameras that capture the results up close for our enjoyment. He has already shown us how to build your own backyard aluminum smelter with the help of some neighborhood kids. After you have built the smelter, melt what ever aluminum you have and find a backyard pool that you can contaminate with the molten metal. The idea was to see how the molten aluminum will react with the cold water. Kevin was probably expecting it to result in some explosion, like when you put hot iron in water, but instead, the metal makes a very cool sound when it hits the surface of the water and then sinks to the bottom., creating some really neat looking shapes. The underwater footage might not be brilliant, but the sound the camera recorded is pretty cool too. There’s another video of Kevin playing with molten aluminum, but this time he dumped a few pounds of the stuff into a fish tank filled with water balls and the results were 1000 times more amazing! If you are looking for a new art form and are not afraid of getting burned, definitely check it out! Backyard Scientists T-Shirts! Limited Edition campaign, buy one now! -

Molten Aluminum Vs. Live Toaster

Feel a bit bored and want to try something exciting? Don’t get your hands dirty, just check out TheBackyardScientist channel on Rumble! Kevin Kohler, a.k.a. The Backyard Scientist has saved many science enthusiasts’ and curious minds’ homes from burning to the ground, by filming insane experiments in his own home and (of course) back yard. Each video comes with a “don’t try this at home” warning for obvious reasons. He has a whole playlist of videos on his channel where he experimented with how molten aluminum reacts with different surfaces and items. For now, the most basic of experiments. Namely, one of TheBackyardScientist’s subscribers, Beth Lancina, suggested " should fill any random household items (metal) with molten aluminum like a toaster!..." Ever wondered what happens when you pour 1000 degree molten aluminum metal on a plugged in toaster? Sparks fly, plastic melts, and toasters everywhere shed a tear. You might be able to notice that the molten metal sticks to everything metallic on the appliance, melts the plastic components, but does not stick to the bread inside? Watch when the slices eject from the heat – they just throw the molten aluminum right off. Check out the channel here on for more interesting experiments.

Guy Creates Huge Mouse Trap, And The Result Is Unbelievable6m19s

Guy Creates Huge Mouse Trap, And The Result Is Unbelievable

Everyone and their grandma has had a pest problem at least once in their life. There are an abundance of ways to get rid of or prevent the appearance of pests in your home. But have you ever wondered what a scientist would do if he got himself in the same situation? In this new video, Kevin Kohler, a.k.a. The Backyard Scientist shows off his latest invention -- a giant mousetrap that obliterates anything that crosses its path. "I've got a bit of a raccoon problem at my house, so I built something to fix the problem," the Backyard Scientist wrote on his YouTube page. "It breaks multiple local ordinances and a few international treaties, but I give you the giant mousetrap." The trap took three weeks to build and cost around $360 to make from supplies like wood planks, car suspension system coils and steel square tubing. The main expenses are the winch and the multiple pipe fittings to adapt the springs to the bar. After many attempts using garage door springs and then coil springs, he finally got it right. For those worried this video is an animal snuff film, don't fret. The Backyard Scientist only destroys objects without a pulse. It's oddly satisfying to watch him use the giant trap to smash a watermelon, coconuts, a fiery model volcano, a mannequin head wearing a hard hat and more.

What Happens When You Put 20,000 Volts Into A Watermelon6m08s

What Happens When You Put 20,000 Volts Into A Watermelon

Ever wondered what would happen when you pump 20,000 joules into a watermelon? Two words. Pink and mist. Kevin Kohler, who also goes by the moniker The Backyard Scientist, has saved us all from spending huge amounts of money on capacitors and throwing away precious summer food by gathering three of his whacky engineering friends to show us exactly what high voltage electricity does to a watermelon. After trying to blow up a watermelon with a smaller capacitor holding about a 1000 joules of energy, Kevin’s friend and electrical engineer Coyt brought over 4 capacitors rated at 20 kilovolts and 25 microfarads each. They came from a lab that used to them to simulate the effects of lightning on materials, so basically, this is like an extension of their experiments. Unlike a battery, which stores power, a capacitor is able to unload all of it’s “juice” in a fraction of a second. A small one has the potential to stop your heart, but when it is as big as the one Coyt brought, it will literally blow you to bits, just like that juicy watermelon. Thank goodness The Backyard Scientist is more concerned about blowing stuff up, than he is about the advancements in science.

Tossing Live Bullets Into Molten Aluminum Is An Explosively Bad Idea4m09s

Tossing Live Bullets Into Molten Aluminum Is An Explosively Bad Idea

Finally, a backyard experiment that might just actually ask for a disclaimer. But Kevin Kohler, our Backyard Scientist isn’t one for disclaimers, so he will just show you what tossing live bullets into molten aluminum and molten pewter results in. Please don’t ever do this at home. Or anywhere else, for that matter. Mixing bullets with molten aluminum creates a hell of an explosion. The result is a volatile spray of the hot liquid metal everywhere, and that’s just a terrible idea. Those things are flying with extreme speeds and no amount of distance can keep you permanently safe. It can end badly, that’s why you should sit back, pop one open and let the Backyard Scientist handle it. In the footage, shot with Kevin’s unlucky GoPro, he tosses 15 bullets at a bowl of molten aluminum and luckily, only three make it in, because the resulting explosion is so huge that I can’t even imagine the bomb that would have happened if all 15 made it in. One cool sequence in the video is that you can see an individual bullet make contact with the molten aluminum and then immediately jump right out of the bowl and then explode into pieces. Lucky it didn't go very far.

What Molten Aluminum Would Do To Flesh5m41s

What Molten Aluminum Would Do To Flesh

When Kovin Kohler, a.k.a., The Backyard Scientist, started playing with molten aluminum in his own backyard, his viewers got concerned about their favorite crazy genius, thinking he might burn himself and get sent to the hospital by playing with the liquid metal. In order to instill some peace of mind, Kevin decided to test out what will happen if molten aluminum actually gets in touch with muscle tissue, or flesh. He took a very juicy looking piece of steak, set it on an angle in his yard, melted some aluminum and poured it over the meat. First of all, the molten metal just rolling off the meat was insane to watch! We thought it might stick to is, like a hot, old pan. Using a thermal camera, Kevin shows that the meat isn’t even hot, it’s just barely warm. You can see from the footage that Kevin himself looks hotter than the aluminum covered flesh and when cut, the steak is still raw inside. So pouring molten aluminum didn’t cook the steak, what about if we actually tried cooking it is a pool of molten aluminum on the stove? Kevin takes a fresh cut of meat, melts a pan full of aluminum and waits for the temperature of the meat to reach 140 degrees, without destroying the meat. The flesh floats in the pool of molten metal and it barely sticks to the meat. The searing caused the fire alarm to go off, but the steak looks medium rare, which means you can’t really cook meat in molten metal, without burning the things completely through.

Check Out What Happens When Liquid Nitrogen Vapor Meets Flamethrower4m35s

Check Out What Happens When Liquid Nitrogen Vapor Meets Flamethrower

While half the United States was literally under fire during the scorching summer of 2016, one evil scientist took to drastic measures to cool down. But he wouldn’t be the evil mastermind if he didn’t test out his brand new invention on everything he would lay his eyes on - including his girlfriend! The Backyard Scientist constructed a homemade liquid nitrogen “freeze ray” that used the pressure of the nitrogen turning from a liquid to a gas to create a powerful cold spray. After playing with his creation and freezing some flowers, things escalated into a showdown between the freeze ray and a makeshift flamethrower. But don’t let us tell you all about the experience, let Kevin do it: “I made a freeze ray! I’m basically a bonafide evil genius now. Freeze your cat, girlfriend, or flowers, the possibilities are endless..! wait no, that’s about it. PS before Jeopardy thinks about suing me for using their music, remember who has the freeze ray now! Kevin: 1 - Alex: 0 “Some notes about the gun: There are commercial liquid nitrogen guns used by dermatologists to freeze warts and skin cancer off. The guy that sells me liquid nitrogen was telling me about them. He says they have a pressure release valve that keeps the pressure at around 70psi. The problem is it’s hard to make a thermos that’s also pressure rated because you have a pressure on the inside of the flask, then a vacuum directly on the other side. They are fragile and expensive. I tried to put a nichrome heating element inside the thermos to increase pressure, but it ended up not working that great. Shaking the thermos made way more pressure!” PSA: Do Not Try This At Home!

This Is What Happens When You Pour Molten Aluminum Into A Pumpkin4m19s

This Is What Happens When You Pour Molten Aluminum Into A Pumpkin

It’s time to do Halloween, Backyard Scientist-style and what better way to decorate your house for Halloween than by using pumpkins. In this episode, the Jack O’Lantern meets his match in a 1000 degree aluminum and liquid nitrogen. The inside of a pumpkin has a pretty interesting geometry. I had the idea to cast the inside to see what it looks like, but the inside of the pumpkin is very fragile and the 1000 degree aluminum pretty much destroys it as soon as it comes in contact with the soft flesh. I thought freezing the pumpkin would provide more structural support, so I froze the pumpkin from the inside out with liquid nitrogen. My thermometer can only measure to -36f (-38c), and the pumpkin was colder than that. Liquid nitrogen has a boiling point of like -300 degrees. Which means it sucks heat from whatever it touches until that object is -300 degrees at which point it stops boiling. Both pumpkins turned out awesome, although they were a bit stinky. There was some slight difference between the two. The one without the liquid nitrogen turned out a bit more chunky and rounded while the one with the liquid nitrogen turned out to be a lot more defined and slim. Which one do you think looked better? Next time I cast any fruits i will definitely be freezing them first!

iPhone in Molten Aluminum4m41s

iPhone in Molten Aluminum

Pick-a-Phone Giveaway: Brandon's Video On Brandon's channel, he runs a lot of "creative durability tests", a.k.a. destroying iPhones in cool ways. In this video, watch as an iPhone is truly destroyed for good in Terminator 2 style, in a vat of molten metal. The metal is so hot that it looks like lava. Check out the insane transformation the iPhone goes through! In yet another of his epic adventures with molten aluminium, Brandon and his guest take us on a journey of destroying an iPhone in a matter of seconds. If you thought nothing beats this monster gadget, see what happens near the end of this video. Molten aluminium oxide near the melting temperature is roughly 2/3 tetrahedral (i.e. 2/3 of the Al are surrounded by 4 oxygen neighbors), and 1/3 5-coordinated, very little (<5%) octahedral Al-O is present. Around 80% of the oxygen atoms are shared among three or more Al-O polyhedra, and the majority of inter-polyhedral connections are corner-sharing, with the remaining 10–20% being edge-sharing. The breakdown of octahedra upon melting is accompanied by a relatively large volume increase (~20%), the density of the liquid close to its melting point is 2.93 g/cm3. We're dying to know if the phone was good for use! Do not try this at home. Facebook: Instagram: Twitter: Website:

Check Out What Will Happen If You Pour Molten Aluminum Over Dry Ice And Liquid Nitrogen5m54s

Check Out What Will Happen If You Pour Molten Aluminum Over Dry Ice And Liquid Nitrogen

The Backyard Scientist is calling you to witness this ultimate battle of hot vs. cold. Today starring is molten aluminum vs. liquid nitrogen and dry ice. The first experiment starts by placing dry ice behind concrete blocks, and pouring aluminum onto it. It is interesting how the aluminum just slid right off the dry ice. This is because a layer of carbon dioxide was produced under the hot aluminum. The entire process is filmed by a FLIR camera, a real thermal camera that enables you to see everything hot and cold that the naked eye cannot witness. Now, he makes an indent into the block of dry ice, but the aluminum just slid right out of the block of ice. Then, he makes a bigger indent hole, and now the aluminum starts bouncing out and dancing around, it is pretty cool. It looks like a lake of molten lava, but it is actually molten metal. The second experiment is to see what happens if you pour molten aluminum into liquid nitrogen. Molten aluminum has a temperature of about 1200 'F and the liquid nitrogen is negative 320 'F which is a very big temperature difference. The molten aluminum falls through the liquid nitrogen like it is not even there, but there is a lot of rapid boiling of the liquid nitrogen, nothing explosive though. The last attempt is to pour liquid nitrogen into molten aluminum. The liquid nitrogen is so less dense than the molten aluminum and it didn't even get the chance to go below the surface, it doesn't come into direct contact with the aluminum because of the massive amounts of nitrogen gas produce.

How To Build DIY Multicolor Fire Tornado With No Moving Parts 4m26s

How To Build DIY Multicolor Fire Tornado With No Moving Parts

There is nothing more satisfying than knowing that you can build something with your own two hands. Kevin Kohler “The Backyard Scientist” demonstrates how to build a simple DIY multicolor fire tornado with no moving parts. The Backyard Scientist is back with a new trick up his sleeve, and this one never gets old! This homemade multicolor fire tornado spins around and weaves itself together with absolutely no moving parts. All you need to do is cut up a glass cylinder and then offset the half-cylinders a little bit to let air flow do its thing to create the fire vortex. The design uses split glass tubes that create convection currents around the fire and various fuel sources that burn with different colored flames. No moving parts, no fans, no squeaky bearings, just fire and forget! Watch as the Backyard Scientist messes around and burns different chemicals, like methanol, lithium, and boric acid, in order to showcase the different colors, like bright red and green, that can be found in a fire tornado. This amazing guy will take you on a magical journey and show you that anything is possible, you just need to have a little patience, talent and knowledge and mix it all together. He will take you down the road, step-by-step, slowly explaining his every move, and eventually he will show you a very neat way to build your own fire tornado! Inspire to Make - Meteorite Ring

Molten Metal Squirt Gun Melts Right Through Many Objects

How cool is this? After noticing that many people were making some very crazy water guns, 'TheBackyardScientist' decided to make a cool squirt gun as well. It isn't your every day water gun, it actually shoots molten metal! He shows us his two very cool squirt gun inventions, they look very impressive! He uses random objects and melts them down, and waits for them to harden. These molds are what he puts into the gun, cool! When the gun squirts out the molten metal, it is so crazy to see that the object he hits, melts right in front of our eyes! This is awesome! Normally you only see this kind of stuff in movies. He even shoots the molten metal at the camera, but of course, he puts glass in between the gun and the camera, you don't want the camera to melt! Luckily the glass didn't break or else that camera would have been melted! Even better, the metal is reusable, no need to throw it out! He continues to use the molten gun in many more different scenarios and it continues to amaze us, awesome! Here's an album of images and a writeup of the gun Heres the schematic for the tesla coil Ill be doing a build video of this in a few weeks due to popular demand!
