The document describes an idea for a new sport called "BlowBall" where a small floating beach ball is kept aloft using a handheld vacuum cleaner. One person uses the vacuum to blow air under the ball to hit it back and forth like volleyball against an opponent on a court of to-be-determined size. The sport is inspired by seeing a beach ball levitated by a reversed vacuum and the creator hopes it could gain popularity like the unlikely sport of curling.
