A fond memory I had as a teenager was making a potato cannon with my brother and dad. The cannon was in a J shape, where the end of the J had a cap for spraying in fuel - like propane or hairspray. Near the end of the J shape we cut a hole to put in an elongated lighter. This went against the design of the video we watched - the video suggested taking the ignition stuff out of the lighter and making it part of the canon. Cutting a hole and just gluing a lighter was the easiest option... but also caused a lot of problems - namely with ignition. During the building of this, right as my mom came home, I looked down the PVC pipe (there was nothing in it thankfully) and asked my brother to click the lighter so that I could check to see if it was lighting or not. My father was not in the room. This ignited the residual fuel in the pipe and burned ALL of the eyelashes off of my left eye. My father came running in and started to scold us, and then my mom came in the room asking what happened. We all hid everything, because my dad didn't want to get into trouble either. We shot many potatoes that summer, and the whole experience made me realize how useful eyelashes are.
