Review title: this was very hard to do
Product review: I bought this for my 4 year old grandson, he loves finding treasures, but we found the dirt in our rock to be so hard to dig that even the adults couldn't manage it, forget even trying the small brush that was provided. We finally wet the dirt and dug in the mud, the rocks and gems were fairly nice once we got them out, but the digging experience just wasn't there. Everything the digging rock and the gems you find were a little smaller than I had expected.
