Why not use a sippy cup like a toddler uses? They have these ones with little plastic membranes on top, that when you apply a bit of pressure open up and release the liquid at that point.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Because there's no upsidedown in space. A sippy cup works by using gravity, you have to turn the cup upsidedown to get the liquid to go to the sippy spout so you can suck it out. In outer space the liquid would just be floating free inside the sippy cup and not near the spout for you to suck it out.
ayo they could never have me on the ISS, I'd be cumming in coffee cups all day
