Hydrogen-Oxygen Rocket
★Exhibit Content: Hydrogen-oxygen separation, Newton's third law ★Interaction: Electromechanical interaction ★Operation: Press the launch button and watch the exhibit generate an electric spark to ignite the mixed gas and propel the rocket launch. ★Exhibit Description: The exhibit consists of a large vertical rocket model base, hydrogen-oxygen electrolysis module, transparent launch tube, rocket body model, and electronic control system. It is a recommended exhibit from the PopsciCat Exhibit Store. Participants press the start button, the device is powered for water electrolysis, decomposing water into hydrogen and oxygen and mixing them in a closed cylinder; press the launch button, the spark plug generates an electric spark to ignite the mixed gas, instantly releasing high-pressure gas, propelling the model rocket upward, intuitively demonstrating the power principle of rocket launch. The grand vertical appearance has a strong visual impact and is suitable for science and technology museums and campus science museums to carry out aerospace and physics-themed teaching. ★Scientific Principle: 1. Rocket flight follows Newton's third law: action and reaction forces are equal in magnitude and opposite in direction. The rocket ejects gas at high speed backward, and the gas exerts a forward reaction force on the rocket. This thrust does not depend on air, so the rocket can continue flying in a vacuum space environment. 2. This exhibit utilizes the principle of water electrolysis: direct current is passed through water, hydrogen is generated at the cathode through reduction, and oxygen is generated at the anode through oxidation. The volume of hydrogen produced is about twice that of oxygen. The hydrogen-oxygen mixed gas reacts violently with a spark, instantly producing a large amount of high-temperature and high-pressure gas, forming jet thrust, simulating the real rocket fuel deflagration propulsion process, helping visitors understand the underlying physics and chemistry knowledge of aerospace propulsion.
