Bouncing Raisins

ages 4-6


4 tablespoons distilled white vinegar; 3 tablespoons baking soda; 1 tall, clear glass or jar; Enough water to fill half the glass or jar; 8 or more raisins

Activity Detail

Try this experiment to make raisins bounce in a glass of water: Add 4 tablespoons of vinegar and 3 tablespoons of baking soda to glass or jar that is half-full of water. Drop about 8 raisins, one at a time, into the water. They may sink at first, but they will soon rise to the surface. They will sink again and rise, creating a bouncing effect, repeatedly for about an hour. This happens because the combination of baking soda and vinegar produces carbon dioxide, the same gas that's in carbonated soda.
