Illustrate Venturi Effect Conceptually

What happens here

To illustrate the Venturi effect conceptually, take a simple yellow tube. Place a lightweight object, such as a small piece of paper or cotton, on a flat surface. Position one end of the tube directly above the object and blow forcefully into the other end. Observe how the air blowing across the top of the object creates an area of lower pressure, causing the object to lift and float, thus demonstrating the basic principle behind the Cyclone 2X's operation.

Goal: Visually explain the Venturi effect using a simple manual demonstration.
