Water floats in the space.It is true...But it is not because there is no gravity

Water floats in space

Water floats in spaceWater floats in space. This is not because there is no gravity or air pressure. But it is due to not being in the orbit. On Earth, we all live under the influence of gravity. This includes water, which is being pulled towards the centre of the planet by gravity.

Water gets its spherical shape due to the tendency of water molecules which stick together. Earth’s gravity pulls the liquid downward and surface tension shapes water into spheres.
Water is a sphere in space
According to scientists, the water drop and the air bubble inside it form spheres in space. Without gravity to tug it down, the forces on the objects are all the same. Hence, the water drop forms themselves into a shape having a negligible surface area. And that is a sphere and it floats.

There is a scientific reason for this. You know that Earth is a curve in shape. And spaceships and all other things inside it have a tendency to fall towards it. But the spaceship itself is also curving in shape. It is moving in a quick sideways movement in orbit. This movement is such that our planet is continually curved away. As a result, the water floats in space.

On the International space station (ISS) as well, it can feel weightless, even though there is plenty of gravity. So, water on the space station behaves exactly as in a zero-gravity environment.
