Curious of How a Soppy Wet Washcloth is Wrung out in Space?
Aboard the International Space Station, hundreds of miles above the earth, astronauts are conducting important science experiments and some, well, not so important ones that are proving to be just as fascinating.
The experiment, called "Wring It Out" was designed by two 10th-graders in Nova Scotia, Canada. Kendra Lamke and Meredith Hatfield won a contest sponsored by the Canada Space Agency to come up with an experiment for an astronaut to perform in micro-gravity.
According to the two students, they hypothesized that water from a wrung-out washcloth would not drip off but rather would remain on the cloth.
Commander Chris Hadfield, an astronaut aboard the International Space Station, saw fit to answer the question and demonstrated what would happen if you wrung a sopping wet washcloth in zero gravity.
Watch the video below to see what happens:
The answer, of course, comes down to surface tension. The cohesive force between water molecules will pull them towards the center of the mass, forming a watery tube. This is all because of the absence of gravity, or rather, the microgravity, at work on the station.
This is not Hadfield first interesting and rather unusual experiment. He's been documenting everything from how to brush your teeth, how to cook spinach to what it's like to cry in space. Click here for the Canadian Space Agency YouTube channel.
recent one answered the question as to what would happen if you cry in space. The astronaut, who has more than 695,000 Twitter followers, says he feels it's vital to show what so few people ever get to see which is why he is documenting his life at the ISS through social media for anyone to follow.
Hadfield is expected to return to Earth on May 13.
