Bernoulli's Dancing Skirt!

Let's watch this video!

The skirt rises as the girl in the video spins. This happens because when the girl dances & spins with high velocity, the speed of the moving air on top of the skirt increases which will create a low pressure area and the speed of moving air below the skirt decreases which creates a high pressure area. Thus, according to Bernoulli's Principle, the difference in pressure makes the skirt rise up.

That is why it is called 'Bernoulli's Dancing Skirt'!
