How do astronauts have meals?

Eating in space is different from eating on the earth. The food that astronauts carry with them doesn't look like the food you eat on the 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(太空舱), the astronaut puts 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 astronaut puts a whole piece in his mouth at a time. There can be no crumb(食物碎屑) floating around the capsule. Meat, cakes and cereal often come in bite-sized pieces.

Astronauts can't 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.
