The Capillary Cup is a zero-gravity cup designed by NASA astronaut Donald Pettit on the International Space Station. The product is an open drinking cup designed to be used in a microgravity environment, developed from Pettit’s desire to drink water without a bag and straw in outer space.
All joking aside, does it work under normal earth gravity?
Well it’s a cup. So I assume so.
I don’t get how you’re supposed to drink out of it in zero g though as tilting it wouldn’t do anything. In the image he hasn’t perpet which sort of defeats the purpose.
I read through a couple of articles on it, and the design is rather smart. To my understanding of the fluid dynamics involved, the liquid in the cup basically sticks to the sides the the inside of the cup, there’s a thin valley like channel that leads up towards the mouth piece. That valley encourages the liquid to travel up to the mouthpiece by capillary action. The mouthpiece holds the liquid in place by expanding outward rapidly from where the channel ends (this is the flange part that looks naughty as everyone has been joking about).
So the drinking action would be to bring the mouthpiece to your lips, and once you make contact the capillary action and surface contact leads the liquid into your mouth.
The liquid would move rather slowly compared to terrestrial allegories of the same, but if you’re only drinking a few sips of coffee or something it shouldn’t be significantly different.
I’m sure this would work in the normal method in earth gravity, but because of the strong gravitational force, I’ve come to conclude that the capillary action of the cup would be massively countered by gravity and it would not function in the same manner on earth. The microgravity environment, IMO, is critical to have for the physics for the liquid flow work as intended.
This is what I came to the comments for! Thanks for the explanation, that’s cool as hell.
I’m guessing you swirl it around and it comes out somewhat controlled either at the top or bottom. Not sure though.
Probably yes. Just need to tilt more so gravity works

Not recommended for tomato juice, fruit punch or red wine.
Kefir?
Mmmm so creamy

Now, find the little man in the boat.
I’m sure the 60ish comments are all going to be about how it looks like a vulva, and there won’t even be a single comment that doesn’t reference the fact that it looks like a vulva
Edit: exactly two top-level comments in this thread don’t directly reference the fact that it looks like a vulva
Vulva.
You think this was posted with the intent of having a discussion about zero g fluid physics?
And then you realize which side you’re on.
Hehe vagina go BRRRRRRRRRRR
That’s the vibrator inside
v3, v5 or v7?
Somewhat ironic that you contribute to that metric with this very comment!
Sometimes you gotta get your shoes dirty when you’re counting turds or something, I’m too tired to say something smart right now
Sorry, had to. That’s Southern gold.
Covert stuff

Did you design this cup? Because you’re a real cunt.
til women don’t know what pussies look like
Okay when you joke about it though, right?

Good grief lmao, he really hit a soft spot there eh
Are you suggesting this incredibly yonic looking device wouldn’t be identified as such by women?
To be fair I would also identify penis-shaped objects as such.
Eh my female friends would do the same. Actually, I’ll share this with them and see how they react…
Update: I sent it with zero context in the group chat. First response “that’s a pussy”
Where’s this idea that women don’t have vulgar thoughts come from?
They’re supposed to be proper and shit, only making babies and keeping to the kitchen
ayo they could never have me on the ISS, I’d be cumming in coffee cups all day

Conversation in a future space Starbucks: Me: “I’d like a triple grande, soy, no foam latte in a to-go vulva.” Barista: “Yes sir…”
Conversation in my local Starbucks tomorrow: Me: “I’d like a triple grande, soy, no foam latte in a to-go vulva.” Barista: “Sir, I have a taser and pepper spray, if you leave now, I won’t call the cops.”
But is he getting up or sitting down?
Thats a vulva
SEX JOKE
HAH
SEX
Wait… what’s that?
I think it’s a kind of cake?

Ah yes that thing where you design something based on something in nature that does what you want…
Stoichiometry or something
Hey now.
