Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat.

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 spaceship, 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 once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cakes often come in bite-size pieces.

Astronauts cannot drink water from open cups. The water would float in drops in the spaceship. The water is put in the special gun. The astronaut shoots the water into his mouth.
