Oooooh! Oobleck!

This is the wildest stuff—and if it doesn’t get your inner kid just a little bit excited, I don’t know what will! I can tell you this—it elicited a genuine “Wow! Cool!” from a 13-year-old who normally reacts with studied cynicism to just about everything these days…

Oobleck gets its name from the Dr. Seuss book Bartholomew and the Oobleck, in which a gooey green substance, Oobleck, fell from the sky and caused all sorts of trouble in the kingdom.

Making Oobleck can be used as a science experiment of sorts, because it is considered a “non-newtonian fluid.” That is to say, it acts like a liquid when being poured, but like a solid when pressure is put on it (for instance, when you squeeze it in your hand). Hit it hard and it feels like you are hitting a wall! Touch it softly and the material will flow gently around your fingers (Hmmm…wonder if there’s a life lesson in there as well?)

Here’s an easy way to make Oobleck—though it will likely still make a mess—primarily because you’ll get carried away playing with it. You may want to put down some newspaper before you begin. Just in case…

Mix approximately 2 parts cornstarch with 1 part water and add a few drops of food coloring (For example 1 cup of corn starch and ½ cup of water). We actually mixed the food coloring into the water and then poured it into the bowl with the cornstarch and that worked well. Mix with your hands (of course)! I would suggest adding the water a little at a time until you get the consistency you want, but if it does get runnier than you like, just add a little more cornstarch.

If you have kids in your life, I guarantee they’ll love making this. And even if you don’t (no, make that especially if you don’t), mix up a batch just for fun!
