For my NASA project I made a cup called The Space Cup that can be used in a zero gravity environment. The cover keeps the water (or any other liquid) inside the cup. The straw makes it so you can drink out of it. The straw has a cap so when it is not being used the water won't come out of the straw. There is a small hole so air can be where liquid was. There is a funnel to fill through the straw, but it will have to be filled in an environment with gravity.
