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)
~Water
~Containers
~Stirring rod (or anything to stir with)
~Ice
~Freezer
~Microwave
Paso 1: Mix it!
Put water in a big bowl/container you adding corn starch until the water becomes extremely tough to stir. It has also been described as a syrupy texture, but you should be able to feel a difference. If you are not sure, you can test it by applying pressure with the poke of your finger or a spoon. You will feel and initial resistance by the fluid and then it will slowly release.
Paso 2: The Fluid Itself
You will notice if you leave the fluid unattended for a spell, it will separate into two parts and solid will be on the bottom of the container. Simply mix it up once again to regain the non-Newtonian fluid texture.
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.
