These are rocks. The rocks will grow into crystals when you add the chemicals to them. We also added dye to the rocks and chemicals.
This is a picture of me putting the rocks into the containers.
I observed the crystals when they were growing. Some looked pointy and some looked smooth. It took 4 days to grow. Isn't that a long time?
My favorite crystal was a pyramid looking one. It was completely clear.
Thanks Grandma Chris!
