The other reason that you can't patent your idea is that it's immediately obvious...a bar on a British patent for many years.
Furthermore. It's like another well known idea utilizing a cannon ball, rope and gloves. (Except that the gloves are hi friction)
The ball is spun on an horizontal axis, while standing on the edge of a cliff. The ball is then allowed to fly off upwards. The hi friction gloves allow one to suddenly grip the rope, thus allowing the spinnee to follow the ball.
