A Canadian astronaut is seen squeezing a wet towel while performing an experiment on the International Space Station in a viral video.
In micro-gravity, even an ordinary object appears wonderful. Earthlings have long been fascinated by microgravity and water.
This incredible combination is promoted in a video that has resurfaced and is going viral on social media. Chris Hadfield, a retired Canadian astronaut, is seen in the video caressing a wet towel while performing an experiment on the International Space Station. Live streaming of footage from the ISS took place in 2013.
Chris begins by displaying a towel that has been truncated to the size of a tape roll. Then, using a water bag, he draws out enough liquid to saturate the towel. He writes to the towel after he is finished. The absence of gravity prevents water from dripping onto the ground. Instead, a gel-like surface develops. It starts with the towel and slowly progresses to Chris’s hands.
The experiment demonstrates how water in space reacts to its environment. On Earth, water management appears to be relatively simple because gravity directs the water molecules to flow, whether they are exiting a bottle or entering our mouth through a glass. However, there is almost no force to move water molecules in microgravity.
In space, the surface tension of water is the only factor at play. In microgravity, the only factor affecting the behavior of a fluid – in this case, water – is surface tension. As a result, astronauts must use straws to extract water from a sealed container.
Something similar is going on in the video as well. When the towel is twisted at both ends and carried over Chris’s hands, the surface tension allows enough water to flow out of the towel.
This is what happens when you squeeze a wet towel while floating in space.
