Bet you never knew fire can come from a grape... an ordinary edible grape. This video tutorial will show you exactly how to make fire shoot out of a grape, and it's easier than you think, or maybe not.
Cut the grape in the middle, almost all of the way through. Peel the fruit apart so that only a thin piece of the skin is holding it together, like a door hinge. Put the grape in the microwave with the cut-side up. Now, quickly watch as sparks and flames fly from the grape. Pretty simple, huh? This may be the easiest science experiment trick to do yet.
