Making baking soda fizz and bubble is one of the easiest experiments you can put together — and it’s so fun. Try a little rainbow science by adding just one little thing to the classic experiment.
The best part about this easy experiment? Somehow each and every time I set this experiment up, the kids are delighted. Actually, I think it’s pretty cool, too!
How to Make Your Rainbow Fizz
(affiliate links used below)
- several colors of paint (we’ve also done it with food coloring)
- pan (we used a pie plate)
- baking soda
- pipettes (we used these pipettes)
Squirt the colors you want to use onto the pan. We used the colors of the rainbow (and pink!). Just give each color a good squirt onto the pan!
Then cover the entire pan with baking soda. And once you have all that baking soda piled on— make it bubble!
Use pipettes to squirt the baking soda — as it fizzes, the colors underneath will bubble up and appear! In these pictures we used apple cider vinegar (I was out of white!) – so it’s a little brown. But still awesome.
