Just popped into my head. If there was a giant 'straw' from the ocean into space, would the lack of gravity have a syphoning effect and draw water into space?
Straws in the ocean!!
You monster.
Shouldn't we be cutting down on our plastic use?
No, the gravity here would suck all the space into the ocean and we'd be left with a load of dissolved ****-all in the water
Only if the straw had antigravitational properties lol!
I'll allow for a bamboo straw
A straw is too wide, you want a capillary. Make sure it has a hole at each end too

Now he's having ago at the pandas.

And put it on a treadmill.
No.
Firstly you need to realise that vacuums don’t suck.
secondly what you have effectively described (assuming the straw contains a vauum not air) is a giant barometer. At atmospheric pressure the water will only rise approximately 33ft up the tube (we more commonly measure pressure in mmHg - as its a somewhat more convenient thing to measure but you can measure a height of water too).

As has been pointed out, it’s air pressure that makes a difference. Although gravity sucks.
You're all so negative- we're going to stick to our guns and make a success of giantstrawoceanexit
Hey, if you use a bendy straw you could make the planet spin faster so birds end up flying backwards. Go for it, I say.

No, you're thinking Dysons
It's a genius idea, just extend it as far as the Moon. Mars would be better, but obviously there's practical realities.
We could drain one of the oceans on earth that no one is using - like the Antarctic, although I'm not sure how the straw would handle the chunky bits.
Then we'd have a nice sea on the moon to go sailing in. Could call it Mare Essteeluna.
I think a whale would get stuck in the straw and block it.
There isn't a 'lack of gravity' anywhere.
How many holes does this straw have?
Hmm, sensing that the straw is not a viable solution to rising sea levels. Giant archimedes screw instead? How far into space do we need to get water before it floats off somewhere else?
Could we not siphon some seawater out of the world's interconnected oceans and in to the nearly dessicated Aral Sea? That would reduce "global" sea levels a bit...
I know there are all sorts of ecological considerations.
But with a long enough straw, pre-filled (following the syphoning idea), wouldn't the water high enough up be above orbital escape velocity? In the absence of some other force holding it in, that would start flinging water out of the top of the straw.
We'd presumably fill it with a jug from the top of the space elevator.
