I planned the rainbow volcano as a fun activity for my toddler-preschool crowd, but surprisingly, the older kids found it interesting, too. This activity results in a bunch of colorful explosions: what’s not to like?

I gave my toddler a muffin tray, adding a few drops of different food coloring to each opening. We only had the basic food colors, so we were learning how to create orange and blue and purple, combining two colors.

Then I gave my toddler baking soda and a teaspoon and he added two teaspoons of baking soda to each opening of the tray.

Finally, I gave him a measuring cup full of vinegar and he had to slowly pour the vinegar over the soda to watch the explosive, colorful reaction.

The kids asked me to repeat the experiment immediately and my toddler asked for it again the next day!
