Today we investigated if raisins move in three different types of liquid water. Salt water, plain water and sprite. I thought the raisins would float in the soda water.
In the salted water the raisins did nothing they sat at the bottom of the plastic cup.
In the soda it had wee bubbles on the outside and moved up to the top and then back down again. There were bubbles on the raisins that made them float to the top.
The fizzy drink had carbon dioxide.
