Hydrogen-Oxygen Rocket
★Exhibit Content: Hydrogen-oxygen separation, Newton's third law ★Interaction: Electromechanical interaction ★Operation: Press the launch button to watch the exhibit generate an electric spark that ignites the mixed gas and propels the rocket. ★Exhibit Description: The exhibit consists of a circular platform, a hydrogen-oxygen electrolysis module, a transparent launch tube, a rocket model, and an electronic control system. It is a recommended exhibit from the PopsciCat Exhibit Store. Participants press the start button, the device is powered to perform water electrolysis, decomposing water into hydrogen and oxygen and mixing them in a sealed 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. This intuitively demonstrates the power principle of rocket launch, suitable for science and technology museums and campus science museums for aerospace and physics themed education. ★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 backward at high speed, 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, reduction at the cathode generates hydrogen, oxidation at the anode generates oxygen, and 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.

★Exhibit Content: Hydrogen-oxygen separation, Newton's third law ★Interaction: Electromechanical interaction ★Operation: 1. Participants use a hand-crank generator to produce electric current for water electrolysis; 2. Press the launch button to generate an electric spark that ignites the mixed gas and propels the rocket. ★Exhibit Description: The exhibit consists of a square yellow platform, a hand-crank generator, a hydrogen-oxygen electrolysis module, a high-transparency acrylic launch tube, a rocket model, and an electronic control system. It is a recommended exhibit from the PopsciCat Exhibit Store. Participants turn the handwheel, the hand-crank generator produces direct current to supply the electrolysis device, electrolyzing water to decompose hydrogen and oxygen, which are stored and mixed in a sealed cylinder; after gas collection is complete, press the launch button, the spark plug generates an electric spark to ignite the hydrogen-oxygen mixed gas, instantly releasing high-pressure gas, propelling the model rocket upward along the guide rail. ★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 backward at high speed, 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, breaking the common misconception that "rockets rely on air for propulsion". 2. Principle of water electrolysis: direct current is passed through the aqueous solution, reduction at the cathode generates hydrogen, oxidation at the anode generates oxygen, and the volume of hydrogen produced is about twice that of oxygen. The hydrogen-oxygen mixed gas undergoes a violent oxidation reaction with an electric spark, instantly generating a large amount of high-temperature and high-pressure gas, rapidly ejecting outward to form strong thrust, simulating the real chemical rocket fuel deflagration propulsion process, intuitively demonstrating the multi-stage energy conversion.
