Did you know that science is the mastermind behind bath bombs?

It's true! Not only do these popular collectibles look beautiful, smell delicious, and create the best bath times, but they're also the result of some fizzy, unique chemical reactions that we can learn from. Creating your very own  using this bath bomb kit is the perfect way to gain a little understanding of Chemistry - and to have a whole lot of fun in the process!

With this hands-on bath bomb kit, kids create DIY fizzy bath bombs while also learning about the chemical reactions behind them! A bath bomb is basically a science experiment, and each contains several ingredients that are mixed and molded into a shape. Once it hits the water, the fabulous fizzing chemical reaction begins!

Use the supplies in this Bath Bomb Science Kit to make your own homemade bath bombs. We even include a raspberry fragrance and a vanilla fragrance, so kids can prepare their bath bombs for a luxurious bath time. With this bath bomb science kit, kids (and perhaps adults, too) will experience the fun side AND the relaxing side of science! From our Resource Center: bath bomb science fair project

Explore different recipe options and different sizes, and discover how changing the amounts of the different bath bomb ingredients affects the fizz factor! Once you've perfected your recipe, your relaxing, fizzy bath awaits. Keep them for yourself, or give them away as gifts!
