Bath Bombs (2-Pack)
What you get
Dip your toes into bubbly bathtime chemistry with this bath bomb 2-pack. Mix up colorful chemical concoctions, then mold them into shape to make two types of bath bombs — animal-shaped bath bombs, and multilayered, planet-themed bath bombs inspired by the layers of the Earth. Then drop your finished bath bombs into the water to see frothy, fizzy chemical reactions — in action!
1. Planet Bath Bombs
Mix together citric acid, baking soda, cornstarch, and food coloring to make a variety of colorful bath bomb powders.
Individual price: $19.95
2. Animal Bath Bombs
Learn about acid-base reactions and the science of molecules while mixing up a colorful chemical concoction, then press the mixture into bath-bomb shape.
Individual price: $17.95
Both projects are delivered together. Each project can make 3-6 unique bath bombs.
