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 to color the flame with some boric acid, and it turned bright green. NightHawkInLight gave me the idea to try powered charcoal to shoot embers and orange flame, worked great!

Well this experiment was not explody enough for me, so I used the same concept to build a propane powered cannon. This is honestly the best gas cannon I've ever used, it is just so simple. You could probably shoot 20 golfballs a minute the length of a football field or farther. The canon shot golf balls over 600 feet in the air!!

Im sure you can do tons of other cool things with this concept, let my know if you want me to try something!

One important thing I forgot to mention in the video is the fit of the object in the barrel. If you completely plug the barrel the gas mixture does not enter the tube, because torch only 'passively' blows the mixture down the tube into the combustion chamber. All the projectiles i shot had some 'slack' in the barrel.

If you followed me on social media, you would have gotten sneak peeks for this video!
