We know that raisins are made from dried grapes.We know that there is no water in raisins but we were wondering if they have air in them, and whether they float or not.
We got a cup and filled it with water. We dropped some raisins into the cup, and waited for them to float. They didn’t.
Next we got another cup and filled it with lemonade. We dropped some raisins into this cup. At first the raisins sank to the bottom, but then the fizzy air bubbles in the lemonade started sticking to the raisins and the raisins started to float. After a while the air bubbles burst and the raisins sank again. They looked as if they were dancing.
