Swimming Raisins

Swimming Raisins | Science Fair Projects | STEM Projects
Ever wondered what would happen if you put raisins in a jar of vinegar and baking soda? This experiment will show you how the raisins will move around in the jar!


The hypothesis is that the raisins will move around in the jar when vinegar and baking soda are added.

Method & Materials

You will fill a jar with vinegar and water, add baking soda, and then drop in a few raisins.
You will need a large glass jar, vinegar, baking soda, and raisins.


The raisins will sink to the bottom of the jar when they are first dropped in, but then they will rise to the top and start to sink again. This is because the bubbles of carbon dioxide gas stick to the raisins and help carry them up to the surface.

Why do this project?

This science project is unique because it shows how a chemical reaction can cause an object to move.

Also Consider

Try this experiment with different types of acids and see if it works in the same way. You could also try using vinegar and baking soda to unclog sinks and drains.
