Mar 13, 2014 · There's a simple reason you can't walk on water: Humans are so big that the force of gravity overcomes the so-called surface tension of water, making us sink.
Have you ever wondered if it's possible to walk on water? In this video, we break down the science behind surface tension and how small creatures like water striders can effortlessly glide...

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 ...

Apr 2, 2020 · To walk across water, water striders could be taking advantage of surface tension and buoyancy. To take advantage of surface tension, all they need to do is not break the surface of the water molecules.
The maximum distance you can walk on water depends on your skill level, the water surface conditions, and your physical abilities. However, most people can walk on water for a few meters at a time. 9.
