Today we did an Oobleck lab, Oobleck is substance made of water and cornstarch in a ratio of 1:1.75 that, when first observed, appears to be in liquid form. When felt with the hand however, and better yet, squeezed, it turns momentarily solid under pressure.
The slapping noise the Oobleck made when thrown on the table, and the way it became crumby, falling apart in pieces, were too prominent observations that made me think it was a solid. The way it dripped and ran down your hand, as well as the wet appearance were what made me think it was a liquid. After feeling the Oobleck and trying to decide which it was more, solid or liquid, I concluded that it was more solid than liquid. Mainly because it was the physical apprerance that made me think it was a liquid, and touching it that made me think it was a solid. I decided to trust touch more because those properties really reflected something solid that couldn't possibly apply to something in a liquid state.
I would think that it acts this way because it's right in the middle between a solid and a liquid. It's such a thick liquid. The molecules have just enough space to move around slowly when their not compressed, but once they're under pressure they pack together into a solid.
