In some Chinese Martial Arts Drama Series, you may have noticed the characters in the shows can walk, run or even fight on water. Is this possible in the real life. The answer is no. Humans can't walk on water. We are too heavy to be supported by the surface tension of the water and not buoyant enough to float. But human can walk on fluids, something like custard.
Custard is a non Newtonian fluid, which means sometimes it has properties of liquids and sometimes it has properties of a solid. When you walk across the custard, you will be doing it quite fast and also impacting the custard quite hard, under those circumstances when pressure is exerted it behaves more like a solid and liquid. However when you stop walking or impacting the custard, there will be no pressure being exerted and this would make the custard behave more like a liquid. When it behaves like a liquid, you will sink into it. That is not all for this post, watch this video to understand more on what I am saying.
