It is also called Oobleck, a great experiment to try at home. Lay a speaker flat on the ground, cover the woofer with plastic wrap and fill it 1/3rd with Oobleck. Turn up the bass and watch the Oobleck dance...preety amazing.

Yes, it is a non-Newtonian fluid called a "shear-thinning fluid."  See "Fluid Mechanics" by Kundu and Cohen.  I carry out a smaller scale version for my undergraduate fluids class.

2500 lbs of cornstarch and a tub! Who would of thought how much fun that could be. Keep this video from your hot tub customers until we invent a filter cartridge for this.

P.S. Might be a while. Reemay didn't work well.
