You can create various types of crystals with your children. It's very exciting as the crystals grow. Crystal growth takes 3 to 7 days for best results. Review: Cool lab at home thing if you like soft rocks - Easy to grow some crystal at home with the kid. Heat some water, dump some powder in, then let water cool, then dump a growing rock thing in the cup. Let sit a couple days and POW/WOW its done. Taking them out and digging the growing rock thing out was a no go. These things are like fine china that break just by breathing on them almost. no lie in my pictures I show they didn't get huge but about the size of the bottom of the growing cup. the tall tower crystals break off so easy and I really hoped that they would dry harder but NO they are still delicate little crystals made only to look at and not touch. at least the plastic LED light base is cool. I plugged mine in to a usb hub in the corner of my kids room to act as a night light. they reflect off the mirror and really brighten up the corner. I do worry that my jerk of a cat might tap them one day and bust them all to hell. good news is that you can just buy a cheep pack of powder and seed growee rock from any random store and use the cool cup to do another batch of crystals. I'll prolly end up buying another one once this one burns out or breaks.
