Ooey Gooey Slimy Fun

What do you get when you mix two parts cornstarch with one part water and add a few drops of food coloring? Oobleck of course! What is oobleck? A slimy, gooey substance thought up by none other than Dr. Suess in his book Bartholomew and the Oobleck. It's also a non-Newtonian fluid. I'm not going to explain what that is here, so click the link if you want a scientific explanation. I was doing this with preschool age kids, so here is how I explained it to them: "Oobleck is very cool, because when you squish it in your hands it feels like a solid, but when you open your hand up, it drips through your fingers like a liquid!"

Every single child loved the oobleck, even the little guys, who love exploring new textures. In case you are wondering, oobleck washes off of little hands very easily, and if some drips on the floor, just wait until it dries (won't take very long) and vacuum it up.
