The Teaching Tank Starter Kit is extremely versatile. It comes with Discovery Book 1 and a bag of Clear Growing Crystals. The Teaching Tank will capture your child's natural curiosity in science and enhance his or her understanding of science through a variety of hands-on activities. Paul Reinbold of Captivation Inc. is proud of the acclaim that the Teaching Tank has garnered. He told TDmonthly that the Teaching Tank has received “…not one, but two prestigious awards from Dr. Toy, the first being one of the 100 Best Children's Products for 2006 and the second being one of the 10 Best Educational Products for 2006.
