What happens here

To illustrate the principle of uplift, the presenter takes a piece of paper and holds it against their mouth. By blowing air over the top surface of the paper, the paper visibly lifts, demonstrating how faster-moving air creates lower pressure and results in an upward force.

Goal: Visually demonstrate the uplift principle using a simple experiment.

What they say

Hide

thought that you need wind to be pushing upward into a structure for it to lift the roof, that's not true. This low pressure creates uplift, just like an airplane wing. Let me demonstrate this principle. The wind flowing over the top of the paper lifts the paper up. This same concept is applied to your roof. In the case of a storm, if debris breaches a window or a door, this pushes your house apart. We rely on anchor bolts, hurricane ties, nails in your sheathing
