How does the Dial foaming handwash dispenser work re dispensing foamed soap?

Aside from being cool-looking, what’s the advantage of foaming soap?

Don’t get me wrong; I’ve raised a couple of yard apes myself, and anything that convinces them to wash their hands more often is a Good Thing. Just curious to see if there was another reason.

I’ve noticed plenty of normal soap dispensers with little pools of liquid soap beneath them. I’ve never noticed a foaming dispenser with a pool beneath it. I assume that’s the reason.
