How to go to the bathroom on the universe?

The question is easy, but the answer is not simple, when astronauts must live in a zero gravity environment. If not strictly controlled, any human waste would leak out and float in the air.

Going to the bathroom on the universe is not simple.

Astronaut Leroy Chiao shared, there is a lot of work to do for an astronaut before going to the toilet on zero gravity, because the toilet has a very complicated design, including many combined parts, not only Just like the earth.

Even the shape of the toilet is like a complex machine with many knots and piping. Even, the toilet is equipped with a camera to monitor the process of going to the toilet to make sure there is not anything out.

The toilet has a two-handed design that holds two sides to help the astronaut sit still, then follow the steps very meticulously. Of course, astronauts are well trained from toileting.
