Non-newtonian fluid

A non-Newtonian fluid is a fluid whose viscosity is variable based on applied stress. The most commonly known non-Newtonian fluid is cornstarch dissolved in water. Contrast with Newtonian fluids like water, whose behavior can be described exclusively by temperature and pressure, not the forces acting on it from second to second. Non-Newtonian fluids are fascinating substances that can be used to help us understand physics in more detail, in an exciting, hands-on way.

Well, I found this video particularly interesting as it shows a comedy show, with a pool filled with non-newtonian fluid. Rather than just a small bowl, why not have a big pool of it! When we run, jump, or even skip on the pool of the non-newtonian fluid, we are applying force on it. Thus, it would harden and as a result, we will not sink! Now let us watch this video of the experiment of floating on liquid.
