  • Spoon
  • A mold or container to use as a mold
  • Small toys or other objects to put inside

The main thing to keep in mind when mixing this bath bomb recipe is that you need to mix the ingredients very well. 

Then once you have them mixed, dividing them up is going to be key. You’re going to do this so you can add in the coloring. And the more coloring that you add, the more of that rainbow look that you’re going for you’re going to get. 

You can even mix colors to get some cool and unique colors, too. 

The other big thing that you’re going to have to worry about is packing the mold tight enough so that the molds hold their shape. Even though they might break apart the first few times, keep trying. You’ll get the hang of it in no time at all. 

As you can see, packing the mixture in tight and then smoothing it over the top is an important part of making these bath bombs at home.

It is going to take about 4 hours or more for the bath bomb to harden so you’re going to have to find some patience in all of this. 

Once it does get hard, gently remove and store it in an airtight container until you’re ready to use it later.
