I know that there have been loads of posts on various blogs on how to make "Treasure Stones" but some recipes differ slightly so I figured I would post how we made them.
First, I started with small plastic dinosaurs...
Then I mixed together:
1 cup flour
1 cup "used" coffee grinds
1/2 cup salt
1/4 cup sand (taken right out of the kid's sand box)
1 cup water
I would recommend adding the water slowly until you have a nice dough mixture, I added in the full cup of water and it made the dough difficult to work with and very hard to dry thoroughly.
I found it best to spoon a small amount in my hand, place my trinket in the middle, slide it on to a cookie sheet and add another glob right on top to close in the trinket.
From the different recipes that I read you can either bake in the oven or dry in the sun for 3 days. I opted for the oven (125 degrees for 20-30 mins, fingers crossed that I did not melt my dinosaurs). As I mentioned above, I think I added to much water as they were not fully dried and had some soft spots and were definitely not rock hard so I put them outside in the sun for an additional day.
Our big guy opted to use Daddy's tools instead of the kid set which made me a little nervous. ADULT SUPERVISION IS REQUIRED WHEN USING "BIG BOY" TOOLS, as you can see in the next picture how close he came to cracking his skull instead of the "stones".
