Our little guy's schedule has been pretty full this week, so we thought it was time to slow down a bit and have some craft time. Given that he LOVES bath bombs, I thought it would be fun to make some crazy colored bath bombs instead of our usual floral version. We were out of corn starch, so we used bentonite clay instead. In hindsight, using the corn starch may have been better as the clay did muddle the colors a bit. Since we were using dark colors it didn't affect the final product too much and he was stoked to use one.

To make your own bath bombs, here's what you'll need:

  • 1 cup citric acid
  • 1 cup baking soda
  • 1/2 cup bentonite clay or cornstarch
  • 1/2 cup melted coconut oil (or a mixture of oils)
  • Food coloring in your choice of colors
  • Mold

Our previous bath bomb post contains links to some of the sources for materials. Check it out here if you're looking for those details.

Mix the citric acid, baking soda, and clay (or cornstarch) in a large bowl until blended. Slowly pour the melted coconut oil into the dry mixture, stirring as you go to avoid activating the citric acid and causing fizzing. Divide the mixture between three bowls (or the number of colors you want to use).

Add food coloring and blend until combined. I had a bit of trouble getting the color to disperse properly so ended up tossing each color into the food processor for a bit to get the color distributed really well. If you do this, start with your lightest color and work to the darkest to avoid muddling th colors.

Now for the fun part! Also the messy part - if you haven't already, but something under your work surface to catch any extra mixture. Begin layering a bit of each mixture into your mold until your mold is heaping. Smash the two halves of the mold together and carefully twist to separate.

Ta da! Crazy colored bath bombs, as designed by your child. I was so impressed with how excited G was about making these. He was very specific about the colors and precise about the layering which resulted in very interesting designs.

Let these guys dry for 24 hours before storing to ensure they don't crumble. Your kids will be begging for a bath!
