Wringing a wet cloth in zero-G

By Grant Jacobs 20/04/2013 1


Last year the Canadian Space Agency (CSA) asked “young Canadians to design a simple science experiment that astronaut Hadfield could perform in space” using items already available aboard the Station. The winning entry, by grade 10 students Kendra Lemke and Meredith Faulkner from Lockview High School Fall River, Nova Scotia (with help from their teacher, we’re told) came up with wringing a wet cloth! –

It’s a great example of the properties of surface tension and the effects of the absence of gravity.

You’ve got to love the use of the wireless microphone, too.

There’s a whole collection of these experiments – I featured another earlier.

I have to admit when I watched this, I wondered about letting the plastic wrapper float off, imagining what might happen if that floated into someone’s mouth. Others have made similar remarks about the little blobs of water and if that might affect the equipment on board. Comments on that welcome!
