Can you produce enough wind to blow a ping pong ball out of a funnel?
It’s a Physics trick. See, the harder you blow, the harder it will be for the ball to leave the funnel, thanks to the Bernoulli Principle.
The way it works is the faster moving air creates less pressure. So when you blow through the funnel you create a current of fast moving air around the ball. That results in a low-pressure area below the ball that allows the higher pressure area above it to push the ball down and keep it from rising.
It’s the same principle that airplane wings use to create lift.
