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