Bubble Blower (Surface Tension of Water)
★Exhibit Content: Demonstration of bubble surface tension and fluid phenomena ★Operation: 1. Pull the traction ropes on both sides of the exhibit; 2. Observe the demonstration effect of the device continuously producing giant bubbles. ★Exhibit Description: This is a recommended exhibit from the PopsciCat Exhibit Store. It is a vertical movable interactive device, mainly composed of a circular base, metal support columns, bubble generation main body, traction rope assembly, built-in fan, and bubble liquid container. Visitors pull the traction ropes on both sides to drive the mechanism to complete the bubble forming action, continuously generating huge transparent bubbles. The bubble surface shows brilliant thin-film interference colors. The exhibit is simple and intuitive to operate, suitable for multiple people to experience simultaneously. In the fun interactive process, it guides visitors to observe the complete process of bubble formation, extension, and dissipation, and understand the science knowledge related to liquid surface tension. ★Scientific Principle: Bubble formation relies on liquid surface tension. The surfactant in the bubble liquid can enhance the toughness of the water film, allowing the film to be stretched into a huge bubble. The built-in fan continuously outputs airflow to fill the bubble with air, and together with the liquid film pulled open by the traction mechanism, the bubble can be stably formed. The colorful patterns on the bubble surface come from the thin-film interference phenomenon. When light irradiates an extremely thin water film, the reflected light undergoes interference superposition, thus presenting changing colorful colors.
