The start (watching the liquid go up the cardboard).
One hour: the inside ones.
Two hours: we brought the outside ones in due to rain.
Three hours: the ones on the left are the ones from outside.
Four hours: the biggest one we got.
I got this crystal kit at Lakeshore Learning. Sarah wanted to try some of them outside but we had to bring them in part-way through the growing because it started raining. The ones that started outside were the best growers of the bunch! My mom & I talked about making rock candy, too, but decided there is too much to do to get ready for Henry's party so we'll have to try that another day.
