It's alive!

Non-newtonian fluids are really awesome. They are essentially fluids whose flow properties are not described by a single constant value of viscosity. This "creeping oobleck" is made out of a simple combination of starch and water. What is really cool about this substance is that if you add force, it acts like a solid rather than a liquid, thus a person moving quickly and applying sufficient force with their feet can literally walk across this "liquid"!
