Product Code: KX1906
Size: 90*90*130mm, Box Size: 98*107*45MM
Weight: About 90g
Material: baking soda + citric acid + plastic accessories + spoon.....

Scientific Exploration:
Chemical rockets use the principle that carbon dioxide produced by the reaction between baking soda and citric acid, as well as the rapid accumulation of gas in a confined space, can cause an airburst to propel the chemical water rocket into the air. Acids and bases are two common chemical substances in our daily lives, and they are widely used in our food, clothing, housing, and transportation. By utilizing the characteristics of baking soda to create a stimulating and interesting chemical rocket, students can learn about the characteristics of acids and bases, truly achieving the goal of education through entertainment.
Scientific Enlightenment:
Rocket propulsion theory is the foundation of space theory. Rocket engines are a type of propulsion tool that can provide powerful thrust to enable spacecraft to achieve the necessary cosmic velocity. Their operation is based on the principle of direct reaction motion, which is particularly advantageous for high-speed navigation.
So, what is direct reaction motion?
According to Newton's laws of motion, two interacting objects always have a force and an opposing force that exist simultaneously, are of equal magnitude, and have opposite directions. Therefore, any kind of movement, broadly speaking, can be considered as an action-reaction movement. For example: one is a ship, which advances due to the action of the ship's propeller on the water, and the opposing force of the water propels the ship forward; the other is a jet engine, which gains forward momentum due to the combustion of fuel in the engine, with the expanding gasses rapidly ejecting backward, thus the engine receives a thrust in the opposite direction of the gasses' ejection.
Scientific Principles:
The two types of motion are indistinguishable, as they are both propelled by reaction forces. However, when examining the characteristics of the reaction forces, there are distinctions between them: in one example, the engine itself does not cause motion; it is merely a source of energy. If there is an engine on a boat without a propeller, the engine's power is not sufficient to move the boat. Therefore, in addition to the engine (the energy source), there is an intermediate mechanism that interacts with an external object (such as water in this case) and bears the resulting reaction force. This intermediate mechanism, which is typically referred to as a propeller (such as the propeller in this example), is responsible for the motion. In the second example, there is no intermediate mechanism; the thrust is generated by the reaction of the combustion gases against the engine itself. We refer to the first type of motion as indirect reaction motion, and the second type as direct reaction motion. Of course, there are also hybrid types that combine direct and indirect reaction motion, such as in a turboprop engine, where part of the engine's energy is transferred to the propeller (the propulsion device), while another part generates direct reaction motion from the combustion gases.
Jet propulsion is a form of direct reaction motion. So, what is jet propulsion? The ejection of material from a propelling object in the form of gas jets is called jet propulsion.
The material ejected by a jet propulsion system is called the propellant; an engine that uses jet propulsion to generate thrust is called a jet engine. When in motion, the interacting objects are the engine itself and the high-speed airflow that is ejected from it. The reaction force generated by the high-speed airflow acts on the engine itself, with the direction being opposite to that of the airflow, which is what creates the thrust.
Science Expansion:
Jet engines are divided into two major categories:
One is the air-jet engine, which is an engine that uses the atmosphere to generate jet streams. For example: using oxygen in the atmosphere as an oxidizer, burning fuel to produce a jet of hot gas; or heating air in a nuclear heat exchanger and then discharging it through a nozzle;
The second is the rocket engine, which is a jet engine that carries all of its propellant on board. For example, it contains oxidizers and combustibles to produce a jet of hot gases.
The thrust and velocity achieved by rocket engines far exceed those of conventional propulsion methods. This engine does not depend on the surrounding medium conditions and can operate in space environments, which ensures that the thrust generated by the engine is constant regardless of the air's ability to absorb it. This feature makes the rocket engine's flight speed much higher than that of any other type of engine. Secondly, due to the direct reaction motion, there are no intermediate mechanisms, and there are no limiting working temperature mechanisms in the main jet channels. This determines that the rocket engine has a simple structure and generates a large thrust.

Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
