The gum-on-the-street-problem got out of hand here in the Netherlands a few years ago. Walking around the city was like walking across a mine field, carefully planning a step ahead to avoid the sticky stuff (and of course dog poo which is still a big problem here as well). The problem got so big that a few guys actually made a good living out of it. They started a cleaning company called Gumbusters. Wearing Ghostbuster-like suits and equipment they wandered the streets and eliminated every piece of gum they came across. I'm not kidding.

I predict these guys will be out of business soon. Chinese designer Gonglue Jiang came up with a smart solution. A pack of gum which has a tiny litter box attatched to the bottom. It even comes with small pieces of paper so you can wrap your gum up! Love it :)
