Art Activity: Fizzy Painting

Let's combine chemistry and art to create a beautiful reaction!

Activity best for children age 2 and up

This activity uses chemistry and art at the same time! When we combine two chemicals, like baking soda and vinegar, we get a fizzy chemical reaction that turns into carbon dioxide. Carbon dioxide is a gas, which is why it becomes bubbly in this experiment. By adding beautiful colors, we have two things – a chemistry experiment and a painting.

Smooth a layer of baking soda on top of the watercolor paper. Make sure to place the paper on top of something you don’t mind getting messy.
