Now who ever thought a quartz watch needed gravity to work right? Maybe this applied to the self winding watch with its internal pendulum that uses the wearer’s movements to keep the internal spring wound up.
Pencils in space are OK I guess, as long as you don’t mind bits of pencil lead floating around in the air. NASA had to worry about pressure differences that the Russians did not, because the US spacecraft used pure oxygen at one fifth atmospheric pressure, while the Russians mimicked earthly air and air pressure.
Neither of the the posters NASA claims are true.
I recall it as 1/3, that is 5psi.
