Usually you don't mind when things get a little slippery, but days like this may have you considering upgrading your umbrella with some up-to-the-nanosecond rainproof technology.
The NanoNuno Umbrella, another brainchild of the Swiss (apparently they're sick of the whole watch-making stereotype), is the latest defense against that pesky rain. At first glance, it looks like a typical full-length umbrella with classic wooden handle, but it actually taps into nanotechnology (yes, your umbrella can do that).
The NanoNuno replaces the flimsy material of a regular umbrella with a textured fabric inspired by the lotus leaf's naturally water—and dirt—repelling surface, which allows any amount of rain and airborne mud (it happens sometimes) to simply slide off the edges. In fact, a good shake is all it takes to get the umbrella bone dry and keep it from leaving puddles and trail marks all over your non-nano doormat...and couch, and pants.
Because as fun as it can be to get wet, sometimes you'd just rather stay dry.
