How do you go to the toilet in space?

From the old ATU Science section:

I'm afraid this link has gone down the toilet.

If we don't refill the interstellar cistern fast, Scotty, we're going to disappear into a black hole:

Wiki:

A space toilet, or zero gravity toilet, is a toilet that can be used in a weightless environment. In the absence of weight the collection and retention of liquid and solid waste is directed by use of air flow. Since the air used to direct the waste is returned to the cabin, it is filtered beforehand to control odor and cleanse bacteria. In older systems, waste water is vented into space and any solids are compressed and stored for removal upon landing. More modern systems expose solid waste to vacuum to kill bacteria, which prevents odor problems and kills pathogens.

Diagram of the elements of the Space Shuttle WCS.

Wiki:

There are 4 basic parts in a space toilet, the liquid waste vacuum tube, the vacuum chamber, the waste storage drawers, and the solid waste collection bags. The liquid waste vacuum tube is a 2 to 3-foot (0.91 m) long rubber or plastic hose that is attached to under the vacuum chamber. It is connected to a fan that provides suction. On the end is a detachable urine receptacle. There are 2 different kinds; for male and female astronauts. The male kind is a plastic funnel 2 to 3 inches in width and about 4 inches deep. A male astronaut would urinate directly into the funnel. He would have to keep 2 to 3 inches away to not get sucked into the funnel. The female version is a funnel that is oval in shape and is 2 inches by 4 inches wide at the rim. Near the rim of the funnel are small holes or slits for air to pass through so an astronaut can place the funnel on her body without getting sucked in. The vacuum chamber is a cylinder about 1-foot (0.30 m) deep and 6 inches wide. On the rim of it are clips where you attach waste collection bags. At the back is a fan that provides suction. The waste storage drawers are where they store the waste. Urine is pumped into one of these drawers. They freeze a sample of urine and solid waste and send it to Earth for testing. The solid waste collection bag is a detachable bag that is made of a special fabric that lets gas but not liquid or solid through. This allows the fan at the back of the vacuum chamber to pull the waste into the bag. When the astronaut is done using it he/she twists their bag and places it in a waste storage drawer.

A first-hand account of going to the bathroom in space:

Some say in the future, space stations will be able to recycle their poo and use it for practical things like repairing the space station structure for example.
