Planet Bath Bombs


What you get

Dive into kid-friendly chemistry with a set of planet-themed bath bombs you crafted yourself! Mix together citric acid, baking soda, cornstarch, and food coloring to make a variety of colorful bath bomb powders. Use a set of molds to shape the powders into multi-layered bath bombs inspired by the layers of the Earth. Then drop your bath bombs into the water to see a frothy, fizzy chemical reaction!

One project can make 3-6 unique bath bombs.

    I liked making them, but I thought the color would stay longer and that it would be more sudsy when I bathed with it.

    My son loved making these and then using them at bath time. He had fun doing the store by step process and doing different color combos. He could not believe how fizzy they were when he got to used the finished product. He made a total of 5 bath bombs. This was such a good gift.
