> I had a water fueled rocket that I lit off in the house on Christmas day.
I had one too. On a nice hot day in mid-summer I wanted to see how high it could go, so I pumped it up two or three times the recommended number of pumps. It blew up and I wound up with a dozen or so cuts from the broken pieces of flying plastic. It was still fun though.
L0L! Those things were great!
