It's below freezing and raining. You throw the waterproof explosives onto the driveway. When the rain stops and the driveway is covered with ice, you set off the tiny explosives to break up the sheet of ice. Then you can easily shovel it, and no harm done. Mind you, the explosives are kind of tiny.-- juliec2, Feb 17 2004 define tiny? laughs +-- nomadic_wonderer, Feb 17 2004 The schrapnel would leave no evidence.-- 2 fries shy of a happy meal, Feb 17 2004 random, halfbakery
