Dancing raisins.

We did an experiment on Thursday using raisins, sparkling and still water. It was great fun. We put the raisins in the still water first and they sank to the bottom Then each child put one raisin in the sparkling water and they all started to move to the top and looked liked they were dancing. We had a long discussion on why this happened and I encouraged them to try it out at home. We left the raisins in the glass overnight and had another chat the following morning . on why they were all at the bottom of the glass.
