How does a humming top work?

A humming top operates using a combination of rotational motion and friction. When spun, the top's rotor creates a stable gyroscopic effect, allowing it to maintain its upright position. As it spins, air is forced through a small opening, which produces a humming sound due to the vibration of the air column. The interaction between the spinning motion and the air movement keeps the top balanced and humming until it gradually loses energy and stops.
