Food that is taken into space is dried, or dehydrated. Dehydrated food does not spoil and takes up little room. Water is added before eating. Meal trays are fastened to the astronauts' legs. Dishes are attached to them by Velcro, and magnets hold the forks and knives.
Space toilets use strong jets of air to blow wastes into a bag below the toilet.
The wastes are dried and stored. To stay seated, astronauts slide their feet under bars at the bottom of the toilet and fasten straps across their legs. Reproduction for personal use is permitted only if this copyright notice is maintained. Any other reproduction is prohibited without permission.
