So like really trying to force water around it the water would have no where to go what would happen?

I desperately want to know what you were imagining might happen when you asked this question.

[โ€“] viking@infosec.pub 31 points 3 months ago (2 children)

A hovering blobb of liquid, equidistant from each wall, most likely.

[โ€“] tonyn@lemmy.ml 45 points 3 months ago (1 children)

That's basically what you get, but the distance from each wall is about an atom thick.

[โ€“] Jolteon@lemmy.zip 3 points 3 months ago

Hey, that atom thick distance allows the water to not stick to the coating.

[โ€“] CanadaPlus@lemmy.sdf.org 1 points 3 months ago

Or maybe explosive splashing.

The long awaited invention of anti-gravity.

The bucket would be dry.

[โ€“] bizarroland@fedia.io 55 points 3 months ago

Basically, the water would be held inside the bucket in the shape of the bucket without getting the bucket wet, because the hydrophobic coating would prevent the water from touching the bucket, however the water would still touch the hydrophobic coating, it just will not stick to the hydrophobic coating.

[โ€“] Fermion@feddit.nl 44 points 3 months ago (1 children)

Well the bucket would get very scared.

hydrophobia is no laughing matter. ๐Ÿ˜‚

[โ€“] tetris11@lemmy.ml 4 points 3 months ago

well then, why are you laughing?!

[โ€“] howrar@lemmy.ca 35 points 3 months ago

You ever use a paper cup? That's basically what they are.

[โ€“] tiefling@lemmy.blahaj.zone 15 points 3 months ago

A black hole would open up, don't do it

[โ€“] walden@sub.wetshaving.social 12 points 3 months ago (1 children)

Like, on the inside of the bucket? It'll still hold water like normal.

[โ€“] stembolts@programming.dev 5 points 3 months ago

However if you put it on the outside of the bucket nothing changes at all and this comment is a pointless thief of your time and attention. Sorry.

[โ€“] Empricorn@feddit.nl 11 points 3 months ago

Do... you think a coating repels water a foot away like some sort of anti-water magnet...?

[โ€“] CanadaPlus@lemmy.sdf.org 10 points 3 months ago* (last edited 3 months ago)

The water sits in it, but only where gravity holds it. There would be a very pronounced meniscus at the top. That is, if you looked closely the water would dip down really far at the edges before it meets the bucket.

It's not that hydrophobic substances can't touch water, it's that the force of surface tension will oppose it. Unless you're an ant, surface tension isn't that impressive vs. most other forces.

Edit: If you have an ant-sized bucket, the water may sit on top of it as a droplet rather than going in.

Don't listen to the jeering goons, OP. Keep asking questions. ๐Ÿคœ๐Ÿค›

[โ€“] intensely_human@lemm.ee 4 points 3 months ago

The water disappears

[โ€“] davel@lemmy.ml 4 points 3 months ago

Pretty sure youโ€™d get one big bead of water. Something much more interesting are superfluids.

[โ€“] black0ut@pawb.social 4 points 3 months ago

Basically the same thing as when you fill a non-stick pan with water. Hydrophobic coatings only repel water in a way so that it doesn't stick to the surface. That's why they use hydrophobic coatings on windshields, so the droplets of water slide easily and quickly.

Granted, the effect is more noticeable with hydrophobic coating than with non-stick coating, but if you were expecting the water to visibly float away from the walls, that won't happen with either. Reality is sometimes disappointing, huh?

[โ€“] davoid@lemm.ee 2 points 3 months ago

makes me want to spray some in a urinal

[โ€“] xilliah 2 points 3 months ago

I'm sorry that's simply not allowed

[โ€“] ShepherdPie@midwest.social 1 points 3 months ago

What would happen if you sprayed your body with hydrophobic spray and then went down a slip-n-slide?

[โ€“] mub@lemmy.ml 1 points 3 months ago

It'll stay empty of course. If make a big enough bucket to stand in and you could go deep sea diving without an airtank.
