I will admit it. I have a love/hate relationship with Moon Sand. The first time we used it, it just wouldn't go away. I swept it, hosed it off, and nothing. Uggg! On the other hand, my kids go crazy for it. It is really fun to play with, I do agree. When I found this recipe for homemade moon sand, I gave in and tried. it. Boy, am I happy I did. It came out nice and pliable and the kids are uber happy to have it again. It isn't hard at all to clean up and is much cheaper than the store bought type. If it starts to dry out, (and it will) just add some more water!
All it takes is 4 cups sand, 2 cups cornstarch and 1 cup water.
Congratulation, you just made moon sand.
