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.

We loved this! We would have loved adding a scent to the bath bomb, but otherwise it worked perfectly!

Everything about this box was absolutely perfect! Not only was it filled with all of the supplies needed, but it also had a fun and easy to understand visual earth science lesson.

My granddaughter is obsessed with Bath Bombs and she loved receiving these for Valentine's Day! She wants to make more to enjoy in her bath!
