Please do this craft only under adult supervision! 
Anything heated in the microwave can become dangerously hot.

 

This is a fun activity to do on it's own or in conjunction with bubble science, hand washing science, or soap experiments.   For even more fun and learning, surf our links on soap making and the history of soap.

What you need:

• Some clear, pure glycerin soap bars (like Neutrogena)

• Shape molds for soap, Playdough, or candy

• Potholders, microwave

What to do:

1. Cut the glycerin soap into small pieces  (1 or  2 inches chunks) or grate them with a food processor.   

2. Put the soap bits into a microwave safe bowl.

3. Microwave on high for 10-15 seconds.  The soap should soften into a liquid.

4. Using potholders, remove the hot liquid soap from the microwave

5.  Pour the soap into the shape molds. 

6. Allow the soap to cool for a few minutes, then carefully remove it from the mold.

Tips: 

If you have trouble getting the soap out of the molds you can try either oiling the molds or placing the soap-filled mold into the freezer for a few minutes.

For some real fun try putting a small rubber toy into your soap!
