[She'll be fine over here in the anti-materialistic corner, bye.

Mei doesn't bother to explain in words -- there's no real point in trying to explain a can opener the way there isn't a point in trying to word how to use a spoon or chopsticks. She merely reaches over and presses the thing to the can, the little -- not-so-sharp -- hook requiring a bit more force before it can really bite in.

And then it's just turn, turn, turn, turn. She isn't using much force, so it's not the best can-opening, but there's enough of a slit there for the food to drop out, if needed.]

It's not a very good one. But it doesn't matter.
