Homemade propane rifle cannon shoots like a sci-fi weapon

Science is fun! Especially when it is used to create a homemade cannon that looks so cool when it fires. This guy connected a self-igniting propane torch to some tubes and then colored the flame so that it pops off green when it blasts. It looks like an alien’s weapon!


The Backyard Scientist writes:

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.

“There going to call the police”

ARGH! You would hope that someone intelligent enough to make something like that would use the correct spelling of “They’re”
