These homemade rocks would also make awesome party favors for a rock climbing party, “you rock” themed party or shape them like an egg for a dinosaur party.
How to make a Blarney Stone with a hidden treasure
Tradition says if you kiss the Blarney Stone you will be given the gift of gab. You will be able to talk eloquently and convincingly. I don’t think these girls need any help with the gift of gab, but we still thought we would make these Blarney Stones. A treasure can be found in the middle of each stone.
Homemade Rocks Recipe
- 1 cup used coffee grounds (or used dry espresso grounds–what we had) If they are too wet I am sure it would change the color of the mixture
- 1/2 cup salt
- 1/4 cup sand
- 1 cup flour
- 3/4 cup water
- (I think it would be very easy to tint this mixture with tempera paint—they might be dull colors when dry)
Mix together dry ingredients and then slowly add enough of the water to make a stiff dough—you might not need all off the water, so add slowly.
Knead the mixture on a floured surface until fairly smooth.
Break the dough into desired sizes. We divided it into 4 equal pieces. Hide your trinkets (super balls, small plastic toys, etc.) or money in the center of each ball of dough.
Bake at 150F degrees for 2 hours (I turned them over half way through) and then air dry 2-3 days (or longer). If you make smaller rocks I would dry one hour in the oven and then air dry 2 days or more. The size of rock and the amount of humidity in your home will affect the drying time. They will look and feel like rocks when dry.
I had hoped to paint them with green and white paint for fun and wait to open them on St Patrick’s Day, but nobody was willing to wait to crack them open with a hammer— let alone wait for paint to dry.
I think we might make some egg shaped ones for Easter.
