GadgetMadness: We find the coolest gadgets first

This new rocket set uses a hydrogen fuel generating launch system to generate enough lift to blast these rockets up to 200 feet in the air. I was concerned at first that some form of electrolysis was being used to create the hydrogen, but it looks like "propellant crystals" are added to water in a mixing bottle to generate the fuel. (If they were using electrolysis, well, that would mean you could create all the hydrogen and oxygen you wanted, and hydrogen is flammable, eh?)

I was the one in my high school physics class to create what was referred to by my classmates as the "H(O2) bomb" by collecting 450ml of hydrogen and oxygen in a beaker, then sticking a match to it. My physics teacher referred to the incident as "a month's worth of detention won't get back the ten years you just took off my life."
