How you wash your hair in space: demonstrated by astronaut Karen Nyberg on the International Space Station.

@wonderofscience I just don’t get how we haven’t mastered the idea of showers in space. Make water spray out the front, have an air intake at the back that goes to a condenser/dehumidifier…. To dry off… Compressed air, like a human sized Dyson air blade.

I’ve been camping and not showered for a week or two… But I could always just dunk my head in the river, even if it was “brisk”. I can’t imagine not showering for months at a time.

@JustinDerrick @wonderofscience That's basically how the Skylab shower worked. It was reportedly quite effective for cleaning, but keeping the water under control was a pain. Showering took about two and a half hours per person, what with the need to track down every stray drop that escaped from the vacuum/separator system.
@JustinDerrick @wonderofscience how to drown your astronauts in 1 simple step

@JustinDerrick @wonderofscience

I'm sure we could, but is it worth the engineering effort and water consumption? People have been giving themselves sponge baths for centuries. They work as well in space as on the ground.
