My idea for a better space drinking cup is to design a small cylindrical container printed from plastic that has a lid with a hole where liquid/powder can be injected and astronauts can drink from a small tip. As expeditions are going farther away to places like Mars, it becomes increasingly more important to consider the weight of on-board items; NASA can consider reducing the weight aboard their shuttles by bringing quantities of drink concentrate, instead of drink pouches. It would work like this: the concentrate will be mixed with water and get injected through the hole. After that, the drink may be consumed by sipping on the tip. One side of the bottle will slope together because liquid is adhesive; it will cling to the sides of the bottle, even in zero-gravity. The smaller rounded sides of the wall will be close so the surface of the liquid will easily get pulled up as the astronaut sips the drink.
