Students will love watching crystals grow before their eyes! This fun and simple school activity is a great classroom supply that makes an excellent gateway into other science experiments. Simply place the included liquid in the 3" diam. dish, insert the 3" x 3 1/2" paper tree and let it soak overnight to grow a gorgeous crystal tree. For best results, pour the water over the tree and soak for at least 24 hours. Largest crystals form within 48 hours.
