1. Preparation: clay, dish soap, shower gel, toothpaste, contact lens care solution, soda water.

2. Pour a small amount of water into the clay to soften it. Do not turn it into a paste directly. Just dip it in water and pull it a few times.

3. Next is the effect of adding detergent and shower gel instead of glycerin.

5. Toothpaste must be added, the mud will become particularly soft.

6. Then add contact lens care solution and soda water for molding.

7. The foaming glue is now ready. In addition, the foaming effect will be better if it is slightly sticky to your hands. It may only be as large as a cup at first, and then it will slowly foam. Remember to stretch it frequently so that the foaming glue will become bigger and bigger.
