Things difficult to perform in space

1. Showering

To have shower in space is difficult. Water spreads everywhere creating mess. Astronauts use pre mixed soap in hot water solution, rub it on their body and clean it with a piece of cloth.

2. Sitting

Man cannot sit in zero gravity. So it is difficult in space to sit in a chair or on table. For this purpose astronauts tie themselves up while sitting in a chair.

3. Urination

You cannot feel that you need to urinate because in zero gravity one cannot feel that his bladder is full of urine and need to be evacuated.

4. Sexual Activity

One cannot perform sexual activities in space as in zero gravity friction between two bodies is impossible.

5. Weeping

Astronauts cannot weep in space. The reason is that due to absence of gravity tears cannot trickle down but they remain in eyes. So weeping is not possible in space.

6. Cooking

Cooking is not possible in space because of zero gravity. The astronauts use canned food in space
