I offered to help out my friend Rosie when she was planning a Star Wars party for Billy, her 3 year old. I wanted to make Treasure Stones, or coffee rocks. You simply make the dough and put a toy inside. This is what they looked like just after being made. I learned that you have to make the dough really dry for it to hold it's shape, and that one batch of it is enough for only 4 small toys.
Here's an obligatory picture of Violett. She really has nothing to do with this post, but we love to look at her anyway!
Here's what they look like when they are mostly dried out. The look grainy and are pretty cool looking. They were still wet a little on the inside so it was easy for the kids to break them open. Rosie's backyard was covered in the remains after the kids got into them!
