Ball in a funnel experiment..Bernoulli's principle and the Coanda effect

The classic Bernoulli's principle demonstration of the ball in the funnel has been a great air pressure experiment for years. The simple version has been blowing into a funnel and a ping pong ball will stay in it as long as there is blowing air. It was time to try it on a larger scale, bigger funnels, bigger balls, more powerful airstreams. The Coanda effect may also be contributing to the behavior seen in this video.
