We at MICHAEL'S SCIENTIFIC COMPANY, the developer and producer of the Science In A bag kits, believe that positive, exciting, and fun experiences in science early in a child's development will encourage him or her to pursue science actively in the future.

"My husband and I have been entirely pleased with Jennifer's enjoyment of the disappearing crystals. She loves watching them appear and disappear. We are especially, excited about the fact that she understands the science associated with the crystals and is able to communicate to us what she has learned."

"I teach middle school science, and the hands-on activity that my students enjoyed the most was the unit on growing crystals and working with your disappearing crystals. And best of all was the fact that each of my students got to keep the crystals when the unit was completed!"
