Remember those little red and white plastic water rockets you'd get when you were a kid? You pumped them up and released the trigger and they'd shoot high into the air? Well, these geek mad scientist types have taken it to the next level and show how to make monster rockets. I'm not even sure these things are safe, judging by their looks...thus, I hereby relinquish any responsability if you build one and wind up blowing your hand off or something. It's all on you. That said, enjoy :)
