Bernoulli's Principle

Two brief demonstrations on Bernoulli's Principle.

Bernoulli's principle states that as the speed of a fluid increases, the pressure within the fluid decreases. It has been used on common inventions and innovations such as the airplane wing.

This can be demonstrated in two ways:
1.) If you place a ball in a funnel and blow into the funnel, the ball does not float, but, rather, appears to be glued to the funnel. This is because the air escaping around the ball is traveling at a high speed which reduces its pressure. The atmospheric pressure is stronger than the air pressure around the ball, so the ball is locked in place.

2.) If you place a ball in a stream of moving air the ball will levitate (even at an angle). The air flowing past the ball is traveling at a high speed. This causes the air to have a low pressure. So, again, the atmospheric pressure is greater than the pressure around the ball and thereby causes the ball to stabilize as it levitates.

is possible and it's pure physics. All is about high speed = low pressure. Check this video: watch?v=AUyczZ3EiZg

......love the CGI effects. no way this is possible. what planet do you live on?!

Thank you

@EVILxCRACKER Where is the comment stating its a magic trick?

[EVILxCRACKER]

Its not a magic trick... you don't need to explain that the funnel is rigged or the air compressor is sucking... If people wanted to know if you were faking it they could just look up Bernoulli's Principle somewhere else on the internet.
