Discover your first steps as a young chemist with this mini kit for growing red crystals! A magical experience to see the crystals form in just a few days!

This kit can also be used as a necessary refill for "Crystal Chemistry."

For crystal growth:

• Ensure that the device containing the liquid is not accessible to children under 8 years old during the crystal growth process.
• Do not place the developing crystals in areas where there are food or drinks, or in bedrooms.

This KIT contains:

• Plastic container with lid
• 1 plaster stone
• 1 coloring agent
• 1 bag with 120 g of Ammonium Phosphate

Necessary items:

• 1 stainless steel pot
• 1 stainless steel spoon

Ammonium phosphate is a water-soluble salt that forms very beautiful crystals in just a few days. To achieve the best results, follow these steps:

1. Measure 200 ml of tap water with the kit's cup and pour it into the pot. Add the entire contents of the bag.
2. With the help of an adult, heat the saturated solution of ammonium phosphate until it boils or until the salt dissolves. Stir with the stainless steel spoon.
3. Once the salt has dissolved, add the coloring agent if you want to obtain a colorful crystal. Place the plaster stone in the center and at the bottom of the plastic cup. Pour the saturated ammonium phosphate solution on top. Place the lid on the cup.
4. Carefully place the cup in a cupboard, in the dark, and do not move it for a few days to achieve a beautiful crystal. Check the growth of the crystal every 2 days.
5. After 8 days, you can pour the water from the cup into a pot and take the crystal that has formed on the plaster stone.

CAUTION! The crystals are very fragile! Place them on absorbent paper to dry. Pour the solution from the pot back into the cup and leave it uncovered to allow the water to evaporate. Stick a label on the cup "Ammonium Phosphate for Crystals". Do not consume! Keep the crystal in the cup after the water has evaporated.
