Bubble Sinking Ship
★Exhibit Content: Bubble dynamics and fluid mechanics, buoyancy law ★Interaction: Mechanical interaction ★Operation: 1. Press the start button to make a large number of bubbles appear at the bottom of the water tank, and the bubbles rise to near the model boat; 2. Observe the process in which, as the bubbles rise, squeeze, and burst, the model boat loses balance on the water surface and gradually sinks to the bottom. ★Exhibit Description: The exhibit consists of a cylindrical water tank and a press rod, with a model boat placed inside the tank. Visitors press the start button, and a large number of bubbles appear at the bottom of the water tank, rising to near the model boat. After gas enters the water, the density of the mixture of water and gas decreases, so the buoyant force on the boat floating on the water surface decreases; as the gas in the water increases, the boat slowly sinks into the water. Visitors can observe the process in which, as the bubbles rise, squeeze, and burst, the model boat loses balance on the water surface and gradually sinks to the bottom. ★Scientific Principle 1. Buoyancy: The magnitude of the buoyant force on an object in a liquid is related only to the volume of liquid it displaces and the density of the liquid, and is unrelated to factors such as the object's own density, state of motion, and immersion depth. Objects denser than water will sink, such as stones and iron blocks; objects less dense than water will rise, such as plastic and wood. Buoyancy comes from the pressure difference between the upper and lower surfaces of the object, and its direction is opposite to gravity. 2. Archimedes' principle: An important principle of fluid statics, stating that an object immersed in a stationary fluid experiences a buoyant force equal in magnitude to the weight of the fluid it displaces, directed vertically upward and passing through the centroid of the displaced fluid.
