This experiment is a classic that you may have seen before. I was inspired by this post at Learn Play Imagine to add a colorful twist to it though. Pour vinegar into baking soda and watch as a frothy combination of liquid and gas erupts before your very eyes! Step it up a notch by adding drops of food coloring underneath the baking soda and you have a fun and festive Christmas science experiment! Evan could not get enough of this!

Materials Needed:

Glass cups

Large bowl

Food coloring – we used red and green

Baking soda


Activity Prep:

1.With your child not looking, squeeze several drops of food coloring into the bottom of the glass.

2. Pour 2-3 tablespoons of baking soda on top of the food coloring in the cup.

3. Do steps 1 and 2 for each color eruption you would like to do.

4. Pour vinegar into a large measuring cup or another glass.


Now it’s time to get your kids involved. Give your child the cup of vinegar and have them pour it into the glass with the baking soda. For smaller glasses you will need about 1/4 cup of vinegar and for large glasses you will need more to get it to erupt over the top of the glass. The baking soda and vinegar will immediately begin reacting and mixing with the food coloring. Your kids will be so excited to see the colorful eruption occur and if they’re anything like mine they’ll be asking to do it over and over  and over again!
