The Deer Cast Results!

I was worried when I checked my comments to see that cement actually heats up when it is setting. I thought our experiment to make casts of the deer prints we found in the snow was doomed.

After the snow thawed and the children gently scraped off the debris, we were thrilled to see the definition of the two part deer hoof. We could see the two tear drop shapes with the division in the middle just like our tracking books showed.

When held upside down, each one looked like a deer foot. It was a success!

If I do this again, I will try spraying the site with cooking spray first and using plaster of paris. Perhaps we would get even more definition that way.
