Kõik toote kohta
Create a cave at home with real crystals! Your treasures look like geodes, round mineral formations with crystals growing inside. Natural geodes are mined in the mountains and split in half to reveal the beautiful sparkling crystals inside the stones. With the 4M Research Kit, you can grow your own geode without leaving home. To do this, you need to conduct an interesting chemistry experiment. In the halves of crystal bowls, beautifully sparkling minerals grow in 5-8 days. To perform the test, you will need safety glasses, rubber gloves, hot water, a measuring cup, and an apron. Follow the instructions carefully. When the powder is added to hot water, it breaks down into small particles invisible to the eye and forms a solution. When the water cools, some of it evaporates and the particles of the material combine again, forming groups with a regular structure. In this way, crystals with flat and sharp edges are obtained. Use one large packet of monoammonium phosphate powder and one small packet at a time to grow crystals in two hemispheres. Save the remaining few bags for the next geode. Do not mix two large packets for one test or it will fail (the powder will not dissolve). The set of the KidzLabs series develops imagination, thinking, curiosity and increases emotional well-being.ATTENTION! Not suitable for children under 3 years: contains small details. Choking hazard!
