Step-by-step tutorial
Step 1
First, we put our bar of soap on a microwave-safe plate and microwaved it for two minutes. The soap expanded to three times its size, which my niece thought was awesome!
Step 2
She put the soap in a large bowl and used her hands to grind up the mixture.
Step 3
Then we added the soap to a food processor and added just a tad of warm water (about 1/4 cup). Then we added our food coloring.
Step 4
She packed the mixture into a cookie cutter, which she used as a mold.
Step 5
Then we let the soap dry before popping it out of the mold. Scrub-a-dub-dub, here's a gift for the tub!
Tip
It takes 24 to 48 hours for the soap to dry completely. (If you try to take the soap out before it's completely dry, the soap will come apart.)
