For Family Night we had an object lesson using corn starch and water (if you have never tried this mixture, I encourage it!) As long as you are moving it around in your hands it is hard and can be shaped, but once you stop, it will drip like water. Very cool. It was something we all could play with, but Bria got a little distracted. I think she got crowded out to tell you the truth. She just can't compete with Tyler, Jake, and Allie. She didn't seem to mind too much though.
