The basic directions included used coffee grounds, salt, sand, flour and water.
What you Need:She mentioned doing this recipe x4, so that is what I did. Here's what my "mudpies" looked like:
For a smaller batch, use:
•1 cup flour
•1 cup used coffee grinds (got mine from starbucks!)
•1/2 cup salt
•1/4 cup sand
•3/4 cup water
•small plastic toy dinosaurs or other treasures
She suggested letting the coffee grounds dry out. That might make it work better, or smell less like coffee, but I did not do this. I figured if you're adding water to the mix, why set it out to dry? So I didn't. In fact, my sand was from our sandbox, that was wet from the lid not being replaced, so wet coffee grounds + wet sand = I didn't add much water...
1. Mix all the dry ingredients together in a mixing bowl.
2. Slowly add the water and knead with your hands until the mixture is like bread dough.
(I did not dry anything out, so I just mixed it all and added more water slowly.)
3. Once you have moldable dough, press it around your dinosaur or whatever treasure you are putting inside. I used mini dinosaurs.
4. You can air dry these for several days OR bake them on a cookie sheet at 150 degrees for about 15-20 or until you poke them and they arent soft anymore.
(My dino eggs were fairly large, so I baked them for about 45 minutes, AND my oven did not go as low as her directions said, so I baked them at 170, the lowest setting I had. I think mine baked for over an hour. Surprisingly the toys were fine. I worried they'd melt.)
I pretty much just put these down the center of my tables where people ate. Once the games started, the kids were able to open a few and keep their prizes. It was a hit! :)
