I bought this while I was there:
I don't know what crystals have to do with space, but yeah. I think I bought it (like I buy most everything) cause I really like the packaging. Like the time I bought a pin-hole camera making set.
Uh, I had it around for a while, and people would come over and ask me if I tried making it, but I only bought it cause I liked the packaging. But, eventually I did make the camera.
I've never used it though.
You can get the crystal growing kit for $7, and the camera kit for $12 if you look hard enough. Apparently there are larger growing kits. I guess you can fill a whole bucket with crystals. I don't know.
