Have you ever wanted to find a way to walk on water? Of course you have. Everybody has. The video above is a quick glimpse at how it’s possible with Non-Newtonian Fluids.
A Non-Newtonian Fluid is a one that has a varying viscosity depending on the amount of stress exhibited. One simple household example of this is a mixture of cornstarch and water, which is known as a shear thickening fluid. In this case, an increase in stress also leads to an increase in the viscosity of the fluid. If you were to slowly submerge yourself in a pool of cornstarch and water, you would fall in since you are not exerting much stress. However, try to run across the pool and the impact of your foot would increase stress enough to make the fluid temporarily act like a solid!
It may sound like fun to run across an entire pool of Non-Newtonian Fluid, but I would imagine it is tough to clean up.
