Canadian mail management recently has offered their employees a novelty - "a squealing umbrella". By pressing the button built in the handle of umbrella the device makes a special sound for scaring away dogs. Recently in USA the umbrella with a bulb on top charging from a battery built in the handle has been created. It is supposed to switch on the bulb during crossing the road in conditions of bad visibility.

But yesterday I’ve lost my umbrella - wished to buy today – and have found this cool info.
