We were testing out this potatoe cannon that my buddy Julian and I made. We put way too much hairspray in. This means there wasn't enough room for the proper amount of oxygen so an explosion could occur. Julian opened it up and looked in carefully while the other guy held the gun. Nothing happened when we hit the trigger. Finally I had a look in, but by this time hair spray had come out and oxygen had come in. When I hit the trigger the second time, FLOOOMP! A huge flame shot out the back and into my face. It just felt like a pleasent warmth. And then all my eyelashes, eyebrows and hair turned a yellowish white and crinkled off. It was cool.
