Observe how raisins will dance in a glass!
Vinegar and baking soda react to form carbon dioxide bubbles. When these bubbles are formed they stick to the raisins and their many wrinkles, causing them to float to the top. When the raisins reach the top, bubbles tend to pop and release the gas which, in turn, allows the raisins to sink back down to the bottom.
