What-to-do poopsy-woo?

OOBLECK! For those of you who have never experienced the joys of oobleck, here's the scoop:

Oobleck is made from cornstarch and water. The term was originally coined in the Dr. Seuss book Bartholomew and the Oobleck, and was later adopted by this fascinating non-Newtonian fluid. When pressure is applied, the mixture acts as a solid and can be rolled into a ball. When the mixture is free of pressure, it returns to a liquid state. My kids and my dear physics buff, Conor, had never known the joys of oobleck, so I whipped up a batch.

Oobleck is made by mixing 2 parts cornstarch to 1 part water (ish...). I just dump a bunch of cornstarch in a bowl and add water until it I like the consistency. That's how I cook, that's how I make goo. A little food coloring is always fun too, but I didn't have any...at least I didn't have any I could find.

The solid/liquid properties are brilliantly displayed on a Spanish TV show as the hosts run across a pool of Oobleck



Here is Conor explaining to me what I had just made:

You're telling me. When we were dating, I remember him referring to his dad as taciturn, and I was in love!

This looks ridiculously fun. I need me some oobleck.

We could make some when you come over, 'cept I'm out of cornstarch now.

Fun fun fun!! Must. Make. Also, this must be what the Dune shields are made of.
