LMAO I can beat that...
I was about 12-13 years old at the time and I was very interested in rockets and chemistry.. so I decided to make a very small pen rocket... but at the time I didnt take notice of my souroundings and I let it off in my study.. expecting nothing to happen like all my other rockets.. but this time I got the mixture right and it worked!!! to bad I was preforming this experiment right next to a can of deoderant and with my sister in the room, not to mention the pile of "black powder" just off screen and my home made bungers lying around on the desk too.. and to top it all off about 2 mins later my fire alarms went off too... LMAO.. I know, I know very irresponsible but I was 12 LOL the video is still on youtube.. if you really wanna see it ill post it up.. but its not that exciting.. just really DUMB of me!
