My daughter found this little box with a paper tree where the ends of the branches had been treated with a chemical. There was a paper tree, a stand and a little tray to place saturated fluid into and then sit the tree in it. AND then you wait (not long) and crystals start forming on the ends of the branches...thicker and thicker... This photo shows the growth after around 10 hours later...but it was quicker growing, for sure! Looks like each "side" of the tree is a different color. Pretty fun. It worked so fast, it could be done during a day at a child's school, if the teacher would set it up for the kids.... It was amazingly FAST!!! If you find one at your local Dollartree...I say to go for it!
