Invisible Air Umbrella Repels Rain: It's more than annoying when, during a rainstorm, your umbrella blows inside out and breaks. It's enough to give you rain rage. But this totally new concept for an umbrella does away with the movable parts that can become useless in the presence of big gust. The Air Umbrella concept from designers Je Sung Park and Woo Jung Kwon is comprised of a simple plastic stick that sucks in air from the bottom of the handle and blows it out of the top forcefully enough to repel falling rain. Although this is a great concept, it hasn't been tested in real world conditions and it's unclear how well it would work under heavy winds or sleet.
