Incredible video shows what happens to a bubble of water in space

"An incredible video shows the Artemis II team experimenting with a droplet of water while in the Orion capsule. The liquid can be seen forming a perfect sphere as it floats around the cabin. At one point mission specialist Jeremy Hansen - who had never been to space before the historic mission - looks through the orb as it flips his image upside-down. He 'catches' the sphere on a straw before 'releasing' it back into microgravity."

"'During the Artemis II mission, astronauts had a fun time playing around with water in the weightlessness of space,' NASA said. 'Artemis II was Canadian Space Agency astronaut Jeremy Hansen's first spaceflight - so his crewmates taught him a lot about the physics of water in space.'"

"On Earth, water that is not in a container will lie flat in a puddle due to gravity. However in space, water pulls itself into a perfect sphere because molecules on the surface attract each other equally in all directions with nothing to flatten them out. A sphere is a shape with the smallest possible surface area for a given volume - meaning when gravity is weak or absent, surface tension pulls the water into a ball."

"Astronauts on the International Space Station (ISS) have also carried out water-based experiments, including wringing a wet cloth to show how the water runs along its surface and 'sticks' to the astronaut's hand. Delighted fans said there is something 'uniquely human' about the mini experiment carried out in space."

Artemis II astronauts experimented with a droplet of water inside the Orion capsule during weightlessness. The liquid formed a near-perfect sphere as it floated around the cabin. Mission specialist Jeremy Hansen, on his first spaceflight, looked through the orb as it flipped his image upside down, then caught the sphere on a straw and released it back into microgravity. NASA noted that the experiment helped teach the physics of water in space. On Earth, gravity flattens water into puddles, but in space surface tension pulls molecules into a sphere because nothing weakens the equal attraction at the surface. Similar water experiments have been done on the ISS, including showing how water clings to surfaces and hands.
