From the desk of the product designer:

Behind the design

We wanted to make the bath bomb experience more educational. Now kids can learn about the anatomy of a planet while making their bath bombs, from core to crust!

    I did this project with my 9 year old and he loved every step! We were worried that the consistency wasn't right but once the bath bombs dried, they held together perfectly.

    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.

    I would love it if you included the measurements for the ingredients so that we could make them again using the equipment that was provided.
