Dancing Raisins

This week we did the Dancing Raisin experiment. "J" loved this one, which I knew he would, but "M" enjoyed the bubbles, too. It involves adding raisins to a mason jar of water and vinegar and then gradually adding baking soda. The acid vinegar and base soda react and create carbon dioxide bubbles. Enough bubbles eventually attach to the raisins to raise them to the top of the jar, thus the dancing. Mainly, the kids liked to keep adding vinegar and soda to watch it bubble up! (This same concept works great for making a volcano as well, which we did last summer!)
