But “magical” is probably not how I’d describe most public drinking fountains.Who among us hasn’t walked up to a drinking fountain, expecting a bubbling stream of life-giving water, only to experience the crushing disappointment of a measly trickle after smashing in that b***on? But I’m beginning to think it’s not the drinking b***on’s fault; they’re actually some of the most elegant b***ons out there. They’re one of the few remaining b***ons where your push directly and mechanically controls the result. They’re over a hundred years old. And all the action happens within an inch of the b***on itself. Photo by Amelia…
