Eating in space style is difficult. Water and other liquids do not flow down in space, so if any were spilled in the space station, it would float around everywhere. Liquids can ruin electronic equipment, so astronauts have to be very careful in space. They drink by sucking water out of a bag, or from a tube stuck to the wall. They cannot put their food on plates because it would just float right off, so they put it in pouches and eat from the pouches. The food they eat is usually dried, because any crumbs can ruin the equipment.Sometimes fresh fruits and vegetables are sent up to the astronauts, but it is very expensive and hard to send it, so they have to bring plenty of food with them.
