Aloha YouTubers, I am The Backyard Scientist! I like to make videos on all the crazy stuff I do. From exploding arrows, to making instruments, molten aluminum to science/chemistry experiments - I do it so you don't have to! I'm always thinking of more stuff to do, if you have an idea, id love to hear it! Almost everything I do can be considered dangerous!! If you insist on trying my videos at home, just remember- if you play with fire, you're going to get burned. Electricity is deadly. Be safe guys :) I love email from subscribers! You are free to share / upload my videos on social media (FB,Instagram,Twitter,etc...) Only if: - you do not run ads on the video or page it's played on (No websites or YT uploads) Reactions, using clips in YT videos is OK as long as it doesn't violate the spirit of FAIR USE. - you credit my YouTube channel AND tag the corresponding social media site. - you may not sell my videos or edits of videos under any circumstance. Anything else, email me.

Rocket Powered Fidget Spinner

Ok thats it, Fidget Spinner trend is over, cause this is the best one ever!! ;) I built a custom fidget spinner out of 1/4in aluminum plate and strapped 3 E sized rocket engines. Really, I just wanted to do this. I saw Stephens video and needed answers. Plus, this gave me an excuse to buy a Plasma Cutter ive been eyeballing for yearssss. (dont tell sandra I could have made this with a jigsaw..) The spinner has a 6 inch radius, so it travels ~37 inches to make a full circle. Its spinning 88 times per second...

DIY Rocket Powered Plane!

Go to http://TheGreatCoursesPlus.com/Backyard for your free trial today! Ive always wanted to attach rocket engines to a styrofoam plane, so I went to the hobby shop and bought all kinds of rocket engines! They come in sizes A, B, C, D, and E. Each step up is 2x as powerfull as the last. I also made my own F class sugar rockets based on Grant Thompsons design, but I must have done something wrong because they kept exploding :( Music: Halcyon Days- Mokhov

Making a Sword with THERMITE!

Usually Thermite is used to destroy things... Instead, I wanted to use it to make something to destroy things with. If you have never heard of it -Thermite is a mixture of Iron Oxide (rust) and Aluminum powder. When you ignite it a vigorous chemical reaction takes place which results in liquid iron. Its used industrially for welding metal, the military uses it to destroy enemy equipment, teachers use it for science demonstrations, and youtubers just melt stuff with it. I made a mold out of insulating firebricks, and set off the thermite over it to fill it with molten steel! David Collier...

Propane Rifle

Aloha fellow scientists! Have you ever seen anything so cool? So after watching NightHawkInLight's video I knew I had to do this. It was easy to do, all I needed was a TS8000 torch, and 10 feet of 7/8 tubing from the hardware store. Inspiration for this video NightHawkInLights video - https://www.youtube.com/watch?v=jXoqw-_uDx4 The torch is self-igniting, meaning it has an electric sparker built in. When the button is pressed halfway, the torch mixes a perfect combination of propane and air into the tube. When the button is fully pressed the torch sparks sending a flame flying through the tube. I tried...

Giant Mouse Trap [Smashes Everything]

Ive got a bit of a Raccoon problem at my house… I built something to fix the problem. It breaks multiple local ordinances and a few international treaties, but I give you THE GIANT MOUSETRAP! It took over 3 weeks to build and cost around $360 to build, with the main expenses being the winch, and the multiple pipe fittings to adapt the springs to the bar.

6 Dangerous Ways to Cook an Egg

In this video I explore some crazy ways to cook an egg, and kind of go into the science behind it. Plus, its a great excuse to break out the flamethrower! Making a squirt gun flamethrower is very dangerous. I get a lot of emails asking advice on building a flamethrower: I can't stop you from doing it, so I will give you real advice below...... If you play with fire you will get burned, and expect/plan for the worst to happen - The gun catches fire and sprays you with flaming liquid. Squirt guns already leak with water, and...

Deadly stink gas from Etch-A-Sketch?? (Hydrogen Sulfide!)

Today I teach you how to make Aluminum Sulfide, a chemical that releases Hydrogen Sulfide on contact with water. Its one of the smelliest compounds in the world, and you can make it with an Etch-A-Sketch and Sulfur! Plus you get to set stuff on fire to make it, aww yeah! I burned 100mmol (15g) of the mixture, and ended up with 8g of crude product. When I added it to water, I collected 200ml (~.25g, 8mmol) of Hydrogen Sulfide gas, thats only an 8% yield (3.4g, 2.45L theoretical yield). Pretty bad! Of course using a proper crucible, and pure...

Molten Iron Vs. HUGE Magnet

Backyard Scientists T-Shirts! Limited Edition campaign, buy one now! - http://shop.crowdmade.com/collections/backyardscientist/ Have you ever wondered what happens when you bring a magnet near 5000 degree molten Iron? Does it attract? Or repel? Maybe it create cool shapes. But most importantly... DOES IT EXPLODE?! I set off thermite over a very large and expensive magnet to finally find out for myself what happens when molten metal meets a magnet. I learned that molten iron is not responsive to a magnetic field until it falls below 1400 fahrenheit, the curie temperature. By then it's solid!
