This is a fun experiment which is quick and easy!

For this activity, you will need: sparkling water or another any clear carbonated drink (freshly opened works best) and raisins

1. Fill a clear glass or beaker with a carbonated drink.
2. Drop raisins into the glass. What happens? Do they sink or float?
3. Sit and watch. They will start to move and dance in the water.

Things you can discuss…
?What is a hypothesis? (Guess what will happen before you do the experiment)
?Why do the raisins sink to the bottom at first? (They are more dense than the water)
?What makes them dance? (carbonated soda releases carbon dioxide bubbles and these bubbles love to attach to the rough surface of the raisins. They act like floatation devices that lift the raisin to the surface of the water.)
?Why do they drop down to the bottom again? (Once the carbon dioxide bubbles reach the surface they pop and the gas is released into the air. This makes the raisin lose buoyancy and fall back down)
