Fun with Star Wars and science!

I got this for my son because he loves both Star Wars and science. He absolutely loved it. You could see growth of the crystals after the first day. He was excited to check every day just how much more the crystal had grown. We even let it grow a couple of more days then the instructions said to. When we got to the point of turning the light on he was just about as surprised, excited, and happy as he was when he opened the gift. This was a great gift that my son and my self could do together and was great fun!
