Does a mixture of oil and water separate in zero gravity?

Inquiring minds want to know.

I'd assume it still would, based on hydrophobic effects, though probably slower?

(Skip ahead to about 30 seconds to get past the annoying intro and into the meat of the video). Basically, the liquids will still remain separate, but you won't get the situation on Earth where the lighter fluid sits on top of the heavier one--the oil will tend to stay as many separate droplets floating within the water.

Thanks, factotum!
