Well this is an ice-breaker.
Watch this Minnesota man jump on a frozen trampoline. Don't ask. Just watch.
Be warned that the video moves at a glacial pace at first. Nathan Ziegler, a school principal who does cold-weather stunts for his "Minnesota Cold" series on YouTube, explains in detail how he prepares the hose and waters down the trampoline. But the actual jump is worth the wait, as shards fly when he hits the surface back-first.
Hey, it passes the time.
