Materials/Tools: white glue, shaving foam, clear water, container, pigment or pigment (optional) and borax water. 1. Add white glue and clear water into the container and mix well.

2. Add shaving foam and mix well.

3. After the shaving foam is stirred evenly, you can add pigment to adjust the color, so I won't do it here. Next, add borax water and keep stirring.

4. Add a small amount of borax water several times and keep stirring.

5. Continue stirring.
