Bath Fizz Experiment with Adrienne Doll
Back Button
Now you can perform an experiment at home with Adrienne Attoms™, Project Mc2's resident culinary chemist (yes, it's a thing!). Make your own bath fizz using safe household ingredients like baking soda, citric acid and vanilla.

Picking Up S.T.E.A.M.

Usually, you use the classic reaction of baking soda (a base) and vinegar (an acid) to create carbon dioxide gas bubbles. This time, we use citric acid instead of vinegar because it is a solid. You can now pre-mix it with baking soda, mold it into a ball, and then activate it later by putting the ball in water to create fizzy bubbles. The other ingredients -- such as vanilla, glitter, sprinkles, and food coloring – just make your bath more relaxing and fun.
