You may remember the recipe for a basic non-Newtonian fluid from grade school science experiments (one part water to one and one third part corn flour or cornstarch), but those trials probably stopped at squeezing the mixture in your hands. While a regular fluid's viscosity wo ...more
A non-Newtonian fluid is a fluid in which the viscosity changes with the applied strain rate. As a result, non-Newtonian fluids may not have a well-defined viscosity. What you need: 1 part corn starch (1cup) 1.5-2 parts water(1.5 cups) Make a non Newtonian fluid. Click through ...more
