and they'd much rather dance with a salt ion. John Pollard explains how two chemistry principles, energetics and entropy, rule the dance floor. Lesson by John Pollard

Basically the oil particles are so big they keep the water particles from exchanging with each other like entropy would prefer them to do. Additionally unlike water the oil is nonpolar meaning it has low energetics with the water and the water cant simply break it down to make it easier to move about. Eventually these forces conspire to force the water to shove the oil particles together and due to the oils lower density and preference to attract itself the oil will eventually float and rest on top of the water.

Everybody is talking about how messed up the analogy is but really if you simplify it enough it's basically just Oil molecules are too big to go in between Water Molecules so the moment they try to push in they're pushed out because the Water is too closely packed

you have to know the information and knowledge relevant to the topic and then you can understand what he said. so to be honest, he is not a good instructor.

Assholes don't blame the creators for this.
You don't have brain to understand this.
Ability to dance=ability to form attractions

reply

why doesn't he just explain the difference between polar and nonpolar substances rather than too much of this dance analogy?
reply

Everything is so perfect, the script, music, narration and all those cute animations.
Thank you ted ed I learnt a lot.
