QUESTION:
How do you take a bath, brush your teeth, and go to the bathroom in space?

ANSWER from Linda Conrad on January 9, 1998:
There is no bath or shower on the shuttle, so astronauts just wash off with wet washcloths, using soaps that you don't have to rinse off. When they brush their teeth, they can either swallow the toothpaste or spit it into a washcloth. Designing a toilet for zero-gravity is tougher. The astronauts use air flow to make the urine or feces go where they want, since gravity will not do it for them.
