Make Clouds (Smoke Rings)

Earth & Home

★Exhibit Content: Atmospheric Circulation ★Interaction: Electromechanical Interaction ★Operation: Press the start button, place both hands on the "palm" pattern; then press down and observe the shape of the smoke rings. ★Exhibit Description: The exhibit consists of a display stand, an atomizer, a rubber ring, etc. After pressing the start button, visitors press down on the rubber ring to make the atomized water vapor inside the stand spray out from the circular hole. The airflow impacts the surrounding air to form a vortex-like circulation, which rises in the form of rings and eventually disappears in the air. ★Scientific Principle: The exhibit is designed as a stand-type device with a circular jet in the center. The ring around the jet is a pressable elastic surface, beneath which a touch button and a smoke machine are hidden. When the flexible rubber-plastic stand surface around the smoke outlet is pressed, pressure is applied to the air inside, accelerating the smoke flow from the central outlet and forming a hollow smoke tube with fast flow in the middle and slow flow at the periphery. Meanwhile, the front smoke is subjected to air resistance, so it diffuses radially outward, forming a smoke ring. This is the process of smoke ring formation.
