Description:
When air is blown through the funnel, the net force on the ping-pong ball is into the funnel since the moving air around the ping pong ball is less than air pressure . The ball can not be blown out and it will also remain in an inverted funnel so long as the air flow continues. The ping-pong ball will also float on a steady stream of air. With practice the ball can be held aloft with the air blowing at it from an angle.
