Got a fan? An antiquated pointy skateboard? An afternoon? Neon spray paint.
1) pull apart the fan case…a dangerous Rad Board is a good Rad Board
2) replace fan blades with small, sharp, non-menacing looking blades
3) hook above components to the less-pointy end of a pointy skate board
4) put a propane tank looking thing on it with some tubes hooking to the non-spray painted stuff
5) spray anything neon yellow that looks boring, in order to awesome things up a bit
6) fire up the fan and tear ass around the block
