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.
