The same person who thought it was a good idea for Santa to bring DS9 a crystal growing kit???
It's not noisy, but it takes several days, and the crystal isn't nearly as big as it looks on the box. Oh well......
My younger brother had a rock tumbler, I remember mom said it "broke" a couple days after Christmas.....wonder what happened to it????? She may have helped that along, that's not something she would want to mess with!
Hang in there......
