Wrapping Wet Clothes In Space: Astronauts Show Fascinating Property Of Water

A video of Canadian Space Agency astronaut Chris Hadfield wrapping a wet cloth in space has become popular on the Internet.

The video is originally from 2013 and has gone viral after it went viral on social media.

The clip shows Hadfield caressing a wet towel. However, instead of falling down the water forms a tube around it. Why here?

Why does this story matter?

  • In the absence of gravity in space, all things appear weightless and it is fascinating to see how things behave differently than they do on Earth.
  • Simple demonstrations in space also show how far humanity has come in understanding scientific concepts, something that is not possible on the ground.
  • And of course, science can be fun if explained in an interesting way.

The wet towel experiment, conducted by Hadfield in 2013, was designed by high school students from Nova Scotia. He won a national science competition organized by the Canadian Space Agency.

The astronaut claimed that the water in the towel stuck to his hand and had a gel-like texture.

Meanwhile, the ‘wet’ cloth ‘floated like a dog’s chew toy.’

Why does water behave differently in space?

The answer is surface tension—the property that allows a liquid to resist an external force due to the cohesive nature of its molecules.

And in the absence of gravity, the water molecules stick together, forming a kind of liquid gel.

So, when Hadfield squeezed water out of the cloth, the surface tension caused it to stick to the cloth or to his hands.

The feeling of weightlessness in space affects the astronauts even after they return to Earth. After coming back here, many of them drop things on the ground for a few days because they forget they are no longer in free fall.
