    Initial crystals grow really well, but my kids and I are having trouble growing the "colossal" crystals. The "seed crystals" keep dissolving in the solution, which is a little frustrating, although I tend to think it's something I'm doing wrong... We're planning to try a third time. Fun to watch the crystals grow!!!
