Ooblek - Fun or Physics?

Ooblek...have you heard of it?  I hadn't either until I discovered a group of first grade students at Cashton Elementary were planning to use the substance as part of a discovery lesson.  What group of engaged and excited six and seven year olds wouldn't be interested in non-Newtonian fluids?  Students were deep in thought as they made predictions, observations, and formed hypothesis about the bowl of strange pink...something in the front of the classroom.  Sure, it was just a basic mixture of cornstarch, food coloring, and water, but to challenge the students to understand a substance that isn't classified as a solid, liquid, or a gas certainly made for an interesting, if somewhat messy, first grade science class.
