I found a recipe for easy to make sidewalk chalk and thought I'd give it a try.
1 Cup plaster of paris
3/4 Cup Water
*** This recipe will make enough to fill 5 of the small disposable cups.*** For me it was perfect since everything is color coded around here.
I decided to use powdered tempra paint instead of liquid just for fun. I was surprised that making sidewalk chalk could be so easy! Why haven't I tried this before? The only thing I would do different is not use the plastic cups. I think paper would be better to help draw out some of the moisture from the middle. The boys are still complaining that the middles are wet. Oh well.
