Some of my kids’ other ideas for naming this were “yucky goo,” “slime chunks,” “goblin guts,” and my favorite: “ghost barf.”
I think it was my brother who came home and showed me this trick when I was a kid, and once, when I homeschooled my oldest son (for all of about five minutes), we tried it making it at home. It was once included in a Martha Stewart Kids magazine (September/October 2004), and was called “Cornstarch Quicksand”. Oh, how I miss that publication. That’s where my kids saw it this week and begged me to make it.
For about 20 cents, this stuff will keep my kids occupied for a good hour. I imagine it’s a fantastic stress reliever for grownups, too. All you need is some cornstarch and water, and you end up with a strange substance that oozes when you handle it slowly, and tough and resistant when you try to force it quickly.
