Bests & Worsts Reviews from Amazon

We bought this kit for a Christmas gift and it was a big hit while we were setting up the experiment. You get 8 crystal mixes and seeds to work with and four silicon growing chambers. You will need to have a space set up where the chambers can sit for 7 to 10 days for the crystals to grow without being moved. One word of advise DO NOT US ALUMINUM CONTAINERS TO BOIL THE WATER AND DISSOLVE THE CRYSTAL MIX. The aluminum will react with the mix and you will end up with crystalline cotton candy instead of crystals shown on the box. The company Discover with Dr. Cool sent us a replacement crystal mix and seed to replace the botched crystal.
