Learn how to grow impressive phosphorescent crystals at home! You can create your own precious collection of real crystals and amaze your friends and family. Read through the entertaining facts included in the instructions and discover interesting information about crystals.
HOW IT WORKS: When you add the powder to hot water, it breaks down into tiny particles within the water. These particles are too small for you to see. The liquid is then referred to as a solution of the powder. In fact, it is called a supersaturated solution because if you mix in more powder, it cannot dissolve. As the water cools, a portion of it evaporates. The water cannot hold all the dissolved particles, and some of them begin to bond together again. More particles join these, and over time, groups of particles are formed. The particles connect in an organized way, creating the crystals you see, with straight edges and flat surfaces. The phosphorescent powder you sprinkled sticks to the surface of the crystals and at the base of the crystals. When charged by a light source and then placed in the dark, the powder re-emits the light waves that pass through the clear crystals, making them glow!
