I Purchased this to see if it was something my grandson would enjoy. Not only did he enjoy it, he woke up each morning and would run downstairs to see how much the crystals had grown the next day! I never dreamed he would enjoy it as much as he did!

Fun and easy for children to do and learn at the same time.

Directions were very easy to follow. It was amazing how fast the crystals grew!! Even before we went to bed the day we made it, they were already showing. You could almost watch them grow :)
