Dr. Cool's Purple Amethyst Crystal Growing Kit, in exchange for honest review from Tomoson. (Scroll down in the Science Fair Section).
I wanted to review the product because I thought it was cool, plus I know a few homeschooling parents, who can benefit from the products. I also love how the products are reasonably priced.
The kit comes with a seed rock, crystal growing powder, an amethyst, stir stick, diorama, and instructions. There is also an activity book with puzzles, games, and mazes.
I been growing my crystals for two weeks.
The picture shows the progress. The glass started off with no crystallization, but within 4 days, the crystals started forming at the top.
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
