Here’s a neat activity your child will love to do again and again, and share with all her friends. Set out a bowl, and have her mix 1 ¾ cups cornstarch with 1 cup water. She can gently lay her hands on the surface and see how her hands sink into the mixture. Next, have her try to move her hands through the mixture quickly—it’s a lot harder!
