Put some cornstarch on a speaker, turn up the volume, and if the frequency is low enough you can get one of these little puppies! Looks like it's alive! Enjoy!

A non-newtonian fluid under stress reacts as a solid. In this case they filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. Update: Liquid Armor is one of this fluid's applications.

Here's another cornstarch and water solution, which becomes a non-newtonian fluid. A Non-Newtonian fluid, has properties that cannot be described by classical fluids. In this video clip, the non-newtonian fluid is a mixture of corn starch and water.
