Normally, you want to soak in a hot tub to relax and melt your stress away. Somehow suspending a hot tub from a bridge seems like it would do the opposite of that.
That's just what these insane Swiss did, suspending a hot tub from the Gueuroz Bridge, 613 feet above the ground. Why did they do it? You'd have to ask them, but they did indeed do it, soaking up there on that terrifying-looking platform with no guardrails.
It probably wasn't relaxing, but that probably wasn't the point. The point was — uh — nope, I still have no idea. I guess Switzerland is really boring?
