Fun kids experiment

Posted on | September 22, 2008 | No Comments

I’m not sure if this falls under the experiment category, but we do it a lot and my kids love it. My kids first did it at school and call it ooblock. At least that’s how they pronounce it and I didn’t have time to look it up. Just take corn starch and mix it with water. It’s best to play around with it until you get the right consistency, we’ve tried quite a few times using different recipes, but it never comes out right.
Put the corn starch in a bowl and add a little water at a time. When you hit it or press hard it’s a solid. When you dig your fingers in and lift, it becomes a liquid. We add food coloring to change the color. It’s really cheap, easy to make and clean up and the kids will play with it for a long time.
