Query: Not too thrilled about it

I found the rocks are really hard to break (I hammered one on concrete for a while before it cracked). Not much "glitter " inside. It was OK, but my 4 YO was not really interested in it, because the inside was not really all that pretty. I think its a fun one-time experiment, but we were not really that thrilled with it.Not the rocks fault - no one can tell what's inside really. :) Maybe we just got unlucky with our batch.
