1. Add 80ml of 95° water to the 200ml measuring cup.
2. Pour a bag of crystal sand into the water.
3. Mix with the plastic stick for 3-5 minutes (until completely dissolved).
4. Then pour the liquid into the hexagonal measuring cup.
5. Let it stand until it reaches a temperature of about 20° (internal temperature), then add the crystal seed to the center of the measuring cup.
6. Sprinkle half of the magic sand from one bag (there should be enough for all the colors). Put the lid on.
7. Open the lid after 24 hours. Then leave untouched for 6-10 days and let the crystal grow.
