[In IB Physics HL, discussing entropy.]

Ms. D: So, imagine that you have a layer of salt and a layer of pepper in a jar. And then you shake it all up so that it's completely mixed up! How do you separate the salt and pepper into layers again?

Preston: Easy. You can just centrifuge it. And then because of the difference of masses, the salt and pepper will separate.

Max: Or you can put a charge on a spoon and attract the pepper particles to it. And the salt won't be attracted because it's not charged... as much.

Brian: Or you can eat it!

Amanda: I think the answer you're looking for is no. It's impossible.

Ms. D: Thank you!!!
