Zero gravity is all fine and well — but not being able to grab a cup of joe in the morning would be a huge dealbreaker for many prospective astronauts. Thankfully, NASA has a solution to the problem.
Traditional cups are useless in microgravity environments. Liquids don't drip or flow in space, so it just sits there in a kind of congealed state. Sure, you could try tipping the cup towards your face, but nothing would come out. Or, if you shook the cup and tried to use inertia to get it out, the liquid would likely spew out in unpredictable ways — a serious problem seeing as, in the case of coffee, we're talking about something that's scalding hot.
