Surface Tension of Water
★Exhibit Content: Science popularization of the principle of liquid surface tension ★Interaction: Mechanical interaction ★Operation: Visitors can experience being enveloped by a giant bubble in the human bubble zone, and can also use different tools to make bubbles in the tabletop experience zone, observing their formation and changes. ★Exhibit Description: The exhibit consists of two main modules: the human bubble equipment and the tabletop bubble experience device, allowing visitors to explore the mystery of liquid surface tension from "micro" to "macro" in an all-round way. In the human bubble zone, visitors operate a lever to raise and lower a giant bubble ring, experiencing the macroscopic effect of surface tension supporting a huge bubble; in the tabletop experience zone, they use tools of different shapes to make bubbles, observe the microscopic phenomenon of bubbles tending to be spherical, and intuitively understand how water's surface tension forms an "elastic film". It is suitable for science popularization displays in science and technology museums, youth activity centers, and physics science exhibition areas. ★Scientific Principle: Liquid surface tension is the interaction force between molecules on the surface of a liquid, which makes the liquid surface area tend to be minimized, so bubbles always tend to be spherical. Through experiences at different scales, the exhibit intuitively demonstrates the effects of surface tension at macroscopic and microscopic scales. 1. Human Bubble Zone (Macroscopic Experience) Core device: A large 304 stainless steel water pool, equipped with a liftable giant bubble ring and an operating lever. Experience process: Visitors stand on a platform in the center of the pool, lower the giant bubble ring into the bubble solution via the operating lever, and then slowly raise it. Under the action of surface tension, a giant bubble will completely envelop the visitor, creating a stunning visual effect. Scientific principle: The formation of a giant bubble intuitively demonstrates the powerful supporting force of water's surface tension at a macroscopic scale. 2. Tabletop Bubble Experience Zone (Microscopic Exploration) Core device: A four-compartment tabletop device, equipped with bubble tools of different shapes and sizes (such as circular, square, and star-shaped bubble rings). Experience process: Visitors can

Experience process: Visitors can dip different tools into the bubble solution, blow bubbles of various shapes and sizes, and observe their formation, floating, and bursting processes on different surfaces. Scientific principle: By comparing bubbles blown from different tools, visitors can discover that regardless of the tool's shape, bubbles eventually tend to be perfectly spherical, which is a direct manifestation of surface tension minimizing the liquid surface area.
