materials/tools: container, baking soda, spoon, water, detergent, contact lens care solution (borax water or washing powder).

The simple steps of making crystal mud without glue are as follows:

1. First, prepare a container, and then dig two spoonfuls of baking soda with a spoon.

2. Pour some water into the container to dissolve baking soda, preferably hot water, and don't pour too much to make a saturated baking soda solution.

3. Pour the cleaning agent into the container to increase the lubricity of the crystal mud.

4. Next, put in contact lens care solution to make the mask shape. If you don't have glasses care solution, you can add borax water or some brands of washing powder.

5. Keep stirring and find that the solution in the container quickly becomes sticky. At this time, crystalline mud is formed, but it is not transparent.

6. put it in a container and let it stand for about 2 days to make the bubbles disappear naturally. it is best to seal the container. if it is not sealed, the water will evaporate and the crystal mud will dry.

7. After nearly two days, you can get very transparent crystal mud.
