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 http://imgur.com/a/tR35G Heres the schematic for the tesla coil https://www.stevehv.4hv.org/VTTC5.htm Ill be doing a build video of this in a few weeks due to popular demand!

Breaking into a massive 1000lb Safe with a Plasma Cutter7m37s

Breaking into a massive 1000lb Safe with a Plasma Cutter

Kevin Kohler, a.k.a. The Backyard Scientist, strikes again. His latest toy – a plasma cutter. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. The machine uses air to push the plasma further through the material, resulting in a cut. As all good scientists go, Kevin starts by attempting to cut something that is non conductive, like a watermelon. The plasma only burns the rind from the outside and barely makes a hole. That wasn't a challenge enough for our Backyard Scientist, so next stop is to see what would happen if you ACCIDENTALLY burn yourself with the plasma gun. The plasma from the gun burns straight through a piece of steak, which means that you will probably need a big bandage in case you forget to put your gloves on. The this walls of the small apartment-size safe was no match for the plasma, so the real challenger comes from a jeweler's safe, weighing at almost 1000lb! The plasma cuts through the thick back wall in about 10 minutes, leaving the concrete padding to be crushed and the insides revealed. Unfortunately for Kevin, the previous owner emptied the entire vault, leaving only one copper penny from the 70s. What ever the booty was, this was one entertaining video!

Turn an old Oven into a Kiln7m47s

Turn an old Oven into a Kiln

Hey everybody, I’ve been busy the past two weeks! I had a great time at Playlist Live, and finished some much needed organization in my garage. I finally got around to building a large kiln to help me make investment molds for aluminum casting. Now I can finally get this laser gun built! Shoutout to Keystone Science! https://www.youtube.com/user/hobcoman I couldn't find any info on any projects like this, so I thought I would have a try myself. I thought an oven would be the perfect platform, it already has a door, space for insulation, and comes with heating elements! The oven was almost exactly $270 to build, which is about $200 cheaper than a used kiln on craigslist. and 1/10 the cost of a new kiln. I could only get it to 820c - 1500f, Real kilns can get to 2300f. I think my kiln could get that hot if I wound my own heating elements with nichrome wire and added another layer of insulation.

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!

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.

Can a Magnesium fire be put out?4m50s

Can a Magnesium fire be put out?

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 it's 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.

iPhone in Molten Aluminum

Pick-a-Phone Giveaway: http://bit.ly/2h31HZT Brandon's Video https://www.youtube.com/watch?v=ui7ZL0YM48A 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.

Pop Champagne with SCIENCE6m01s

Pop Champagne with SCIENCE

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 https://rumble.com and watch them from the safety of your own couch. This video is somewhat safer, though it might hit you on the pocketbook pretty hard. Kevin uses an ultrasonic cleaning device to see how various fizzy drinks will react, in comparison to, say the Coke and Mentos experiment. The ultrasonic cleaner creates bubbles through a process called cavitation, and the bubbles together with the mechanical vibrations in the water lift the dirt from the objects immersed, thus cleaning them. In fizzy fluids, however, it causes the CO2 to release quicker than normal, which in turn creates the canon effect. After a few tries with the open soda bottles, the time came for Kevin to test how the ultrasonic cleaner will open a bottle of champagne. Looks like the bottle was sitting in the heat of the sun for too long, so the first one didn't even get to be submerged in the cleaner. The second one almost got in the water, but the third one endured for nearly half a second, before popping the cork with incredible speed and bursting the delicious contents of the bottle up in the air.
