Upside-Down Water Phenomenon
Discussions center on a physics puzzle or GIF showing water not spilling from an inverted bottle or cup, with debates on mechanisms like atmospheric pressure, vacuum, surface tension, siphons, and air bubbles.

What about... turning it upside down and let graivity do its job?
Is this a case of water finding it's own level?
Doesn't model air pressure, so no siphon :(
I wonder if it has something to do with surface tension
Please expound upon why it doesn't hold water...
Wouldn't this design create a vacuum in the reservoir?Edit: (reservoir = bottle)
Wouldn’t the end up floating into the air?
That's an informative but unsatisfying gif. What if the residue on the top leaks down?
If the siphon is in the middle of the cup, it won't be activated by tipping, because tipping won't increase the level at the centre.
I don't think this would work without air.
