Canadian astronaut and current International Space Station commander Chris Hadfield is objectively wonderful. While he clearly has a high-pressure and busy working life, what with all the 'being in space' and everything, he also has a fair amount of free time, and seems to spend that mostly trying to entertain the internet.
Some of Hadfield's exploits have including taking videos of himself crying (for research), chatting to William Shatner, playing the guitar and playing around with bubbles.
His latest experiment was simply to take a soapy dishcloth and wring it in zero gravity.
The results, as usual, are completely hypnotic, and counter-intuitive.
Take a look above - and check out some of the best photographs he's taken from the ISS observation deck below.
