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)
Step 1: Mix it!
Step 2: The Fluid Itself
As you poke and prod at the mixture, you can see and feel (if you use your hands) the mixture turning solid into liquid or vice versa. Get hands on! The texture is great to feel and will keep you occupied for hours on end!
After messing around for a bit, add more corn starch. This results in a more solidified liquid and you can better feel the reactions.
