A team of Chinese designers have created the umbrella of the future.  This invisible umbrella, or air umbrella, was designed without using metal poles or a canopy like a regular umbrella requires.  Instead, the air umbrella is simply a wand-like device that keeps the rain off of a person by blowing air out of the top.  It has a switch at the bottom that allows you to control the size of the air canopy which can stretch to be over a meter in diameter.  The device uses a rechargeable lithium ion battery to operate.  The benefit of the air umbrella is not having to walk around with a wet umbrella.
