Once in a while we see a gadget so perfect, so inspirational, that we cannot believe it didn't exist before now. The Water Pistol Umbrella is such a gadget, and it's a convergence gadget to boot.

The masterstroke here is to use the run-off water from the brolly to fill the water pistol. Of course, firing a slug of water at people already desperate to avoid getting wet in the rain is likely to get you a sound beating, but still, who lets danger stand in the way of a practical joke? If this concept ever makes it to market, we're sure Woz will buy them by the container-load.
