I just read an article over at space.com about a guy going to launch himself in a self made rocket using hydrogen peroxide as fuel. Apparently, you inject the HP into a canister that has a stack of silver screens. The HP reacts violently to the silver and instantly expands to 600 times its origanal volume. Kewl. Except he uses 90% HP,not the 3% you have under your sink. Man, I'd love to go into space. Maybe this is the ticket!!
