I have never beenable to shave with a safety razor without slicing my face, so I use a rotaryelectric razor instead. In weightlessness they work just as well, and thewhiskers are captured inside the shaving head. But how does one clean out the whiskersin weightlessness? On Earth, you simply open the head and shake them out. Doingthat up here would be a disaster. So once a week, when vacuuming theaccumulation of lint, dust, and detritus against the air inlet filters, Ivacuum my razor. I hold the vacuum cleaner hose between my legs, and use bothhands to carefully open the shaving head in front of the suction. A cloud ofwhiskers jumps out, appearing like a miniature asteroid field, then quicklydisappears into a black hole, with no chance of escape.
