Dried fruit in fizzy drinks.

One of our science investigations this week is to see what happens when we drop raisins into a fizzy drink. We put a couple of raisins into a bottle of lemonade and small bubbles immediately attached themselves to the fruit. These small bubbles lifted the fruit upto the top of the bottle. When these bubbles burst then the fruit started to sink. More bubbles attached to the fruit and lifted the raisins again.
It worked better in the lemonade rather than the sparkling water.
