Recommended age: 8 years + Box dimensions: 8.5 x 8.5 x 9.5 cm Take your first steps as a little chemist with this mini box to grow your own red crystals! A magical experience to see crystals forming in a few days! This kit can also be used as a reserve for Crystal Chemistry. For crystal development: Make sure that during crystal development, the container containing the liquid is out of reach of children under 8 years of age. Do not place the developing crystals in areas where there is food or drink, nor in bedrooms. This KIT contains: plastic container with lid; 1 plaster stone; 1 dye; 1 sachet with 120 gr of Ammonium Phosphate Required elements: 1 stainless steel pot and 1 stainless steel spoon Ammonium phosphate is a salt soluble in hot water that forms very beautiful crystals within a few days. To get a good result, follow these steps: 1. Measure 200 ml of tap water with the kit glass and pour it into the pot. Add the contents of the sachet in full. 2. With the help of an adult, heat the saturated ammonium phosphate solution until it boils or until all the salt has dissolved. Mix with a stainless steel spoon. 3. After the salt has dissolved, add the dye if you want a colored crystal. Place the gypsum stone in the center and on the bottom of the plastic glass. Pour your saturated ammonium phosphate solution on top. Put the lid on the glass. Carefully place the glass in a cabinet, in the dark, and do not move it for a few days to obtain a beautiful crystal. Follow the development of your crystal every 2 days. After 8 days, you can pour the water from the glass into a pot and take the crystal that has formed on the gypsum stone. ATTENTION! The crystals are very fragile! Place them on a paper towel to dry. Pour the solution from the pot into the glass and leave it uncovered this time to allow the water to evaporate. Stick a label on the glass saying Ammonium Phosphate for Crystals. Do not swallow! Keep the crystal in the glass after the water has evaporated
