Long ago, an executive at the Coca-Cola Company came up with an plan to teach the world to sing in perfect harmony.
All around the world, Coke bottles were distributed with fill lines on them, and when people drank the Coke to that level, they blew across the top of the bottle and get it to resonate with a soothing pitch.
People were supposed to sing at that pitch, but long before anyone got in tune, the resonance from the bottles caused the earth’s core to wobble and explode.
The remaining debris field left a trail like the trademark swoosh.
