What makes oobleck do what it does???

Question

my class is inviting over a preschool and we need to know what makes oobleck do what it does

Answer 1

http://en.wikipedia.org/wiki/Oobleck

And links therein.

Google "non-newtonian fluid" or "shear-thickening fluid" for lots of really detailed technical information.  Interestingly, these STFs are being proposed for use in body armor.

Answer 2

It's fictional. So it does whatever the author wants it to do.
