I love these concept ideas that are somewhere right on the line between genius or the stupidest idea ever. An umbrella with a coffee cup holder in the handle sounds like a great idea if you like coffee and live in a rain area (target market: Seattle). But on second thought, umbrellas are not the most steady of things to hold; one giant gust of wind and you’re soaked from both coffee and rain. At least the rain can wash the coffee stain off your pants (and there it goes back to genius). Designed by Jung-Woo Lee.
