Simple science experiments using kitchen and pantry items are fun to do and a great way to help your kids learn. Get them into the kitchen, follow these simple steps and watch the bouncing raisins go up and down, up and down.
What you need:
- a tall clear glass or jar
- baking soda
- eight or more raisins
Number of players:
Begin by half filling your glass or jar with water.
Then add the vinegar and baking soda to the water.
The mixture in the glass will begin to fizz.
Drop the raisins one at a time into the glass.
The raisins may initially sink to the bottom but eventually they will rise up and then sink, then rise again.
Children should be able to watch the raisins bounce for up to an hour.
