Wringing out Water on the ISS - for Science! (English)

...CSA Astronaut Chris Hadfield performed a simple science experiment designed by grade 10 Lockview High School students Kendra Lemke and Meredith Faulkner. The students from Fall River, Nova Scotia won a national science contest held by the Canadian Space Agency with their experiment on surface tension in space using a wet washcloth...

...how a microgravity environment could influence an experiment. Their experiment "Ring it out" investigates the effects of weightlessness on the reaction of water after being wrung out of a soaked washcloth. Their hypothesis that the water would not drip in microgravity but rather remain on the washcloth was proven correct. In the absence of gravity to pull the water down, it took a shake or a quick squeeze from Commander Hadfield for the washcloth to release the water.
