Getting stuck walking around in the pouring rain is annoying enough, but even once you're out of the storm you're generally stuck with a soaking wet umbrella to deal with. That means wet pants and a big puddle wherever you decide to put the thing. The preciously named NanoNuno umbrella uses nanotechnology to dry off completely after a good shake. The umbrella steals its design from the leaves of the lotus flower, leaves that dry off immediately after the rain because of a surface that's covered with fine-grained nanostructures. Like the leaves, the NanoNuno doesn't absorb any moisture, so once you shake the water off of it there's no drying necessary. Best of all, you don't need to wait for this technology to become available, as you can buy it now for about $94. You'd better be wearing expensive pants that can't get wet, cause that is one seriously expensive umbrella.
