Eating in space is different from eating on earth. The food astronauts （航天）carry with them does not like the food you eat on earth.
Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the space capsule（密封座）, the astronauts put the water back. He “shoots”hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag.
Other foods come in bite-sizes. The astronauts put whole piece in his mouth at a time. There can be no crumb（碎屑）. Crumbs would float around the capsule and get in the way. Meat, cake, and cereal（谷类）often come in bite-sized pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth.
Eating in space is not easy. Astronauts must learn to eat this way.
