When air is blown through the funnel, the force on the ping-pong ball is into the funnel. The ball can not be blown out. It will also remain in an inverted funnel so long as the air flow continues. The ping-pong ball will also be held aloft by a steady stream of air. With practice the ball can be held aloft with the air blowing at it from an angle.
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 .

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.
