Got a problem with birds hanging around? Some folks do, and for them we present the WhirlyBird Repeller. Marketed by two guys in South Carolina bothered by birds on their dock, the repeller spins and clacks in the slightest breeze, chasing birds away and stopping them from roosting. Sounds dumb, unless you’ve been one of the poor unfortunates who’s had to clean up after the feathered foulers. Check it out for yourself at their site, and be sure to watch the video. Sometimes the simplest inventions are the best.
