We've had two ice days this week. The first one on Tuesday wasn't really icy at all, but we stayed home all day. Thomas's school was cancelled so it was a long day. By the end of the day I had to pull out some new things to keep the kids busy and happy.
I made Thomas so "ooblek" it is just cornstarch and water and a little food coloring. When you hit it it is hard, but when you pick it up it is like a liquid. It is fun stuff! Here's the recipe: 2 cups cornstarch, 1 cup water with food coloring added to water. Just mix it the best you can.
