Hi there,
My daughter has asked for a crystal growing kit for her 5th birthday which is coming v soon. I would like something relatively easy to use and that produces crystals which she can keep (the crystal trees look good but they don't last long). The reviews online have been a bit mixed. Does anyone have any recommendations? I know most kits tend to be for older kids but I will obviously help her. I remember growing crystals on cotton when I was little and they were great but that was some time ago!
Thank you!
