To me, the smell of fresh- made coffee is
one of the greatest inventions.

Slowly add the cold coffee and vegetable oil and mix as you go. Knead the playdough thoroughly and store in a zip-lock bag. This recipe makes a nice full gallon size bag of playdough.
I have had a recipe for coffee grounds playdough for some time and I have finally made a batch. I love it and cannot wait to see the kids use these 'play-grounds'. Here's how---
3+ c. flour (you may need more depending on the consistency you like)
1 c. salt
2 c. coffee grounds (your local coffee shop may be delighted to give you bag like mine does)
1 c. cold coffee
2 tablespoons vegetable oil
First mix the flour, salt and coffee grounds in a large bowl. Mix until blended. It will be lumpy but the color should be fairly uniform.
