Levitating Ball & Bulb - Little Shop of Physics

The video tutorial explains the dynamics of airflow around a ball, demonstrating how air moves and creates forces that stabilize the ball in an airstream. Using Newton's third law, it shows how the ball and air interact to maintain stability. The tutorial also demonstrates using a blower to visualize these concepts and explains the importance of the ball being lightweight and round for stability in the airstream.

What are the two crucial characteristics of the ball mentioned in the text?

How does blowing air over a light bulb create lift?
