Amazing 4K video shows how a weightless blob of water behaves in space


Water is super weird in weightlessness

Instead of flowing like it does on Earth, water on the International Space Station pools in circular blobs that can float through the orbiting space laboratory. (Water holds its shape in this way due to surface tension, which keeps the ball of water in a sphere.)
