Bernoulli's Law

A few days ago our class learned about Bernoulli's Law. Bernoulli's Principle states that "as the speed of a moving fluid increases, the pressure within the fluid decreases." After that, we presented our ideas of Bernoulli's law. Some of them included:
Waterfalls, and rivers. Some people presented ideas like this; Blowing on a piece of paper, blowing on a balloon, and a hair dryer blowing a ping pong ball. All of these exercises prove that, the faster a fluid (a fluid can a liquid or gas) travels over a surface, the less time it has to push on that surface. Therefor, the surface moves in that direction. Two key things to remember are; Speed of the fluid is inversely related to pressure. (AND..) Motion is always towards the area of low pressure.
