This super easy experiment illustrates Bernoulli's Principle. The idea is that, as a fluid (this can be either a gas or a liquid) increases in speed, the area around it simultaneously undergoes a decrease in pressure.
What exactly does this mean? Think for a minute about the shape of airplane wings. They're not exactly straight, but curved instead. In fact, airplane wings are designed so that when they cut through the air, more air is directed over the top than the bottom. This means that the air over the top of the wing will actually be moving at a higher velocity than the air moving underneath the wing. This leads to a lower pressure area above the wing, a higher pressure area underneath the wing, and therefore, lift––what keeps our airplanes flying!
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
