whats your worst or best april prank you did to someone that had to do with a car
mine was takin old fashioned shaving cream - freezing it a in liquid nitrogen and peeling the metal can off of the frozen foam
take frozen foam and gingerly place in back seat and place another frozen foam in the glove box
wait for the foam to defrost...and expand......and expand some more.
works best with cars that have tinted windows.
