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.

Had lots of messy fun with this crate! My son loved created the bath bombs and my youngest loved watching it fizzle up. It was fun for all of us. At first we all had a hard time getting the right consistency for the bath bomb but eventually got it. I always love how they provide everything you need!

My daughter had fun with these but they were challenging to put together the different layers. I also think I needed to add more water because all but one fell apart when they dried ?
