- Technically speaking, walking over pure water isn’t possible. The only way it can be done is by converting it to a high density fluid or one with high viscosity. Also, if you think you can run at 108 km/hr (30 m/s), then you’ll have the ability to run across water.

Mar 13, 2014 · Take water striders. Using dyes and high-speed video, researchers have learned how the long-legged insects skate so effortlessly along the surfaces of ponds. By vigorously rowing along the surface, striders create swirls that help propel them forward, all without rupturing the water surface.

The amount of water displaced by the body is equal to the volume of the submerged part of the body. Therefore, if the density of water increases somehow, then the weight of the displaced volume of water also increases, which in turn increases the buoyant force, making it easier for the body to float. Water density depends on a number of factors: 1....
When we ride a bike, the wind pushes against our bodies, slowing us down. This is due to thefriction we experience from the air particles. Similarly, when we are underwater, we experience drag force. This quality of the fluid to resist force or inhibit motion is called the viscosity of the fluid. The viscosity of the fluid is directly proportional ...
The viscosity of a fluid is not a constant; it changes when the characteristics of a fluid are changed. Some fluids have enough viscosity to be able to support the weight of a human body under the right conditions. Oobleck is nothing but a mixture of corn starch in water and can easily be made inside your kitchen. What’s special about this is that ...

Jul 17, 2012 · The phenomenon is not only dramatic, it's almost instantaneous. If the foot of a running human smacks into the fluid at a speed of 3 feet per second (.9 m/s), a huge stepping stone, two feet (.6 m) thick, springs into being beneath the surface in less than 50 milliseconds, Waitukaitis estimates.
Jul 30, 2012 · Walking on water. Scientists explain why a liquid can sometimes act like a solid. This cornstarch and water goo looks like a liquid, but put your hand on the surface and pull up, like a researcher here, and the goo sticks and rises with your hand (before gravity takes over and it drops).
