Sean got a pack of science experiments for Christmas. This one lets you grow color-changing crystals.
He sorted the colors after dumping out the pack.
Put each color in a plastic dish and added water.
Got excited because he is officially a Jelly Crystologist (at least in our lab)!
Then we waited while they absorbed the water (actually up to 300 times its weight).
The next day... they are gooey crystals. He put them into the test tube to see how the colors blend.
They lasted a few days on the counter with him mixing and playing.
Then they were sent to the lab refuse bin.
