Dancing Rasins

Question 1

The Teacer put raisins in a beaker of 7-up. The raisins sank but then bubbles formed around them, making them float. This happens because 7-up has carbon dioxide, which makes the raisins less dense. When the bubbles pop, the raisins sink again. This repeats until the 7-up runs out of carbon dioxide. Adding more 7-up speeds up the process.
