Baking Soda Experiment

Carbonated beverages are  amazing.  You can make your own with Baking soda in sweetened water.  Baking soda.

It has magical powers when baking over flour and water…but what about raisins?

Or in my case we will be using Craisins since I haven’t been grocery shopping in awhile.

Dance Craisins!

Dance!

I ended up adding a little extra baking soda to my mixture to make my Craisins a bit more animated in their dance.

If you want to simplify the experiment, use soda instead of the baking soda and the water.  The carbondioxide in the carbonated beverage makes the raisins rise.  Watch this video to see it in action!

Why baking soda causes fruit to dance

The vinegar and baking soda create carbon dioxide bubbles, the same gas that carbonates soda pop.   Bubbles will gather under the raisins until there's enough fizz to raise the raisins to the surface. When the bubbles pop it causes the Craisins to fall.

Be sure to dance along with your Craisins.
