playdough fun

The boys and I donned our aprons, got our cooking gear out, and whipped up some homemade playdough today. The kitchen is such a great classroom (reading, measuring, following directions, fractions, chemistry and physics are all included.) and what could be more fun to learn with than playdough?
I remember playing with homemade playdough thanks to my mom. She even put different scents (I think she used mint, orange, lemon... Jean, do you remember?) in it to make it smell good. In the past, I've been too lazy or practical to make it myself when you can buy it so cheaply, but B's mom gave Oliver this really cool cookbook for Christmas that has a few crafty fun things to do in the back, one of them being playdough. So, we went for it and had such a good time. I must say even I was so impressed with how it came together!
So, I'll leave the recipe with you in case you want to try. There are many different varieties, but this one is really simple.

1 cup of flour
1 cup of warm water
2 teaspoons of cream of tartar
1 teaspoon oil
1/4 cup of salt
food coloring

Mix all ingredients adding food coloring last. Stir over medium heat until smooth. Remove from pan and knead until blended smooth. Place in plastic bag or airtight container when cooled.
(FYI, it was easy for us to let each boy make the recipe in his own bowl and then repeat it. now we have four new playdough colors!) Have fun... and let me know if you try it!
