NASA’s Coffee Cup Is Designed Specifically To Not Spill In Zero Gravity

      I can’t stop thinking about how wild it must be for our circulatory system to experience zero gravity

    2. The Surface tension of the coffee in relation to the acute angle causes the fluid to ‘climb’ up the length of the acute angled side of the cup. This happens because the pressure experienced by a liquid is equal to the surface tension/the radius of the liquid. The radius is reduced due to the small angle of the cup; therefore, the pressure is greater and the fluid ‘climbs’.

    3. Caption is stupid.

      In zero gravity water sticks to surfaces theres no need to design it to not spill.

      Bit its designed in such a way, that the coffee actually collects at the opening so you can sip it.

    4. Unrelated – I don’t know what it is but every time I see an astronaut video in zero gravity it always looks like they’re having trouble breathing lmao

    5. Ok so on another thread I saw a comment that said the primary design is for drinking coffee, and obviously the liquid stays in the cup in zero-G.

      BUT…it was designed this way specifically for coffee. In space taste is massively dulled. Especially when drinking through a straw. So you can barely taste coffee when you drink it from a straw/bag in space. Smell plays a big role in taste (as a lot of people discovered during COVID). Either this cup design, you have to put the large mass of liquid coffee in front of your nose, and then you obviously sip from the vulva shaped spout. Drinking coffee from this cup, in space, gives astronauts the ability to enjoy a “fuller flavored” coffee. I’m not a coffee snob…but a lot of people understandably drink it simply for the taste and aroma. This cup helps with that.

      Labia space cup. Who’d have thought those three words together would someday be thing.

    7. For some reason this made me ponder the question, “Why do we never see the toilet on the space station?” (While simultaneously recalling the Donovan song, ‘Intergalactic Laxative’ – it would, “get you from here to Mars”.)

    8. I think coffee wouldn’t spill out of any coffee cup in zero gravity. This design actually helps “spilling” in the sense that it lets the coffee flow out of the cup.

      We all know what the inspiration for the cup was, dont we? Or am I just super horny?

      Even though I know there is no up or down in space my brain won’t let me believe it won’t spill until I see it flip upside down

    11. She’s a little bit crazy looking, do they stick astronauts on stimulants or something while they’re up there?
