Erupting Rainbow Science Experiment

When we spot a rainbow in the sky, my kids go wild! So when I told them that we were going to create our very own rainbow, they were jumping up and down, ready to go!

This Erupting Rainbow Science Experiment is perfect for little kids as well as big ones. It’s a super easy activity to put together. In fact, you probably already have everything you need to get started!

Supplies needed:

Vinegar Baking Soda Food Coloring Ice Cube Tray

Step 1: Put a smidge of baking soda down in each section of their ice cube tray.

Step 2: Next, add a drop of food coloring to each section.

Step 3: Now for the "erupting rainbow" part. I let each child pour cups full of vinegar all over their ice cube tray.

Step 4: And each section fizzed up with colors everywhere!
