This DIY Propane Rifle Is Explosive

The Backyard Scientist’s propane rifle looks super cool when it fires. The spark and the propane going through the tubing create a neat effect, making it look like a sci-fi rifle. It is mesmerizing.

It is pretty easy to build, though it’s always dangerous to play with propane and fire. You’ll only need a few simple components: a self-igniting propane torch, some 7/8 inner diameter tubing and a plastic bottle of some sort for the muzzle end. This guy added boric acid to make the flame green. If you want an orange flame with some sparks, add some powdered charcoal.

This is a fun and beautiful weapon. Well, not really a weapon, but it is a great way to have fun with science. I could watch that firing effect all day long.
