What Are Those Giant Balls on Power Lines For? (Bizarre Reason)

Why are there giant orange balls hanging from power lines? Not for electricity—for survival. In this episode of Weirdward Bound, we dig into the strange history of aerial marker balls: the bright plastic spheres that make nearly invisible power lines visible to low-flying aircraft. What seems like a simple piece of hardware turns out to be the answer to deadly wire-strike crashes, a governor’s near-miss, helicopter linemen working on live high-voltage lines, FAA regulations, and an unexpected second mission—saving millions of birds. It’s one of those everyday sights that becomes way stranger the closer you look.
