Spa Lab Bath Bombs

20 Brilliant & Bubbling Recipes!

It’s the bomb! This DIY science kit makes bath time magical with a kaleidoscope of fizzing colors, enveloping aromas, and foaming bubbles.

Featuring custom bath bomb molds, fizz powder, bubble powder, color, scent, liquid glycerin, and a book, Spa Lab Bath Bombs goes beyond the basics and promises a special surprise in every bomb. By experimenting with colors, different amounts of ingredients, and special molds, young scientists can make signature bath bombs that reflect their individual personalities and preferences.

As they create their own bath bombs, kids will learn about acids and bases, carbonate reactions, measurement, proportions, aromatherapy, color mixing, and skin care through hands-on explorations using the materials and components. Learn to create basic bath bombs using the sphere, flower, and bitty star and heart molds, plus more complex creations like the Crazy Daisy Flower Bomb that zips around the tub and produces lots of colors and foam and the Shooting Stars bomb that shoots stars as it floats across the water.
