Did you hear the news? Raisins dance! The kids dropped raisins in Sprite...expecting them to sink to the bottom. They did but them ended up riding back to the top! We found out all soft drinks have a special gas called carbon dioxide dissolved in them. As the gas comes out of the spaces between the molecules of liquid, it stuck to the raisins. There were lots of bubbles...so they lifted the raisins all the way to the surface. Once the bubbles break the raisins would sink again!
