Our matter will turn into a solid when pressure is exerted on it, and will turn into a liquid when little or no pressure is exerted on it.
"It's not that this fluid doesn't have a well defined viscosity (because we can mathematically define the fluid viscosity) -- it's that this fluid's viscosity is defined as a function of the rate of shear - that is, the fluid acts more viscous as you increase shear - a dilatant fluid"
Materials needed for this experiment:
~Corn Starch (About as much water as you are using)
~Stirring rod (or anything to stir with)
