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

    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.

    Eh nothing interesting. The water would be in the bucket but pool and bead much quicker, instead of spreading and getting the bucket ‘wet’. Kind of like a hydrophobic windshield coating.

    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.

      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.

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

    The actual surface of the bucket won’t make contact with the water in it. There will be a thin film acting as a barrier between the water and the surface of the bucket.

    What would happen if you lather yourself in soap so you’re really slippery and then you sit in a bath?

    Actually you’d probably hurt yourself getting into the bath so maybe don’t try this.

      I think with a jump and just the right angle of entry you can probably slide down the sloping face …and probably end up with two broken legs and a tap half-way up your asshole.

      Maybe I’ve been watching too much Looney tunes

    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?
