How do you clip your nails in space? Short answer: very carefully! (Stray bits of material floating around your space vessel can be a problem.) In this video shot on the International Space Station, Commander Chris Hadfield shows us how he solved the problem.
(Bonus space fun: keep an eye on his watch as it floats loose around his wrist.)
Commander Hadfield played a song with Barenaked Ladies live from space after trimming his nails. Not bad, Commander!
