This one’s for datan0de, latexiron, physicsduck, and anyone else on my flist who appreciates this particular brand of science gone mad.

Inappropriately rocket-powered items. Includes all kinds of bizarre vehicles and not-quite vehicles fitted by various madmen with rocket engines, including but not limited to a rocket-propelled shopping cart (made even more terrifying by the close proximity of the red-hot combustion chamber to the…err…driver) and a rocket-powered street luge (because the only thing more dangerous than shooting down the asphalt at sixty miles an hour while only centimeters from the ground is shooting down the asphalt at a hundred and sixty miles an hour while only centimeters from the ground).
