My design is for when astronauts are out of the ship they can carry water and food. There is a part of my object that can be tied on to the astronauts belt. There are two compartments one to hold food and one for water. There is a hole on the water side, so the astronauts can drink it like a water bottle. The top of both sides come off so, you can refill both. You put dried food in the food part. Hopefully this will help astronauts store food and water longer when out on space walks and when in the shuttle.
