There are many kinds of science learning toys that are required for the above activities. Air rockets are one of the science toys that are widely used recently.

In the meantime, prior art related to the air rocket for scientific toys has been specifically described in the prior art document. Hereinafter, the 'toy rocket' presented in [Document 1] will be described as an example.

The rocket for a toy of the prior art described in the above-mentioned [1] includes a frame, a frame fixed to the center of the frame, a frame for mounting a rocket for a toy to be fired, an air hose connected to the frame for discharging air, A rocket body which is fired by pressing the airbag is separated from the air in the air by the rocket body and the airplane, and the rocket body is freely dropped, And then falls after a further distance therefrom.

Another example of another prior art is the 'simple air rocket launcher for learning' presented in [Document 2]. The prior art of the above-mentioned [2] has an air storage unit in which an air-backflow prevention valve is installed at one side and a multi-stage joint in which a discharge path is formed at the center, And a rocket body portion having a diameter capable of being inserted into and withdrawn from the induction pipe.

However, the scientific learning air rocket constructed as described above can learn only the scientific principle that the air rocket flies into the air, and it is possible to combine the booster rockets of various stages, ignite sequentially from the first stage rocket, There is a problem that the scientific principle of the multistage rocket that takes the method of separating the rocket structure that has been made is not explained concretely.

In addition, the conventional air-rocket for scientific learning is built in one piece, so it falls into the air and then falls at a high speed when falling to the ground, which limits the students from learning additional scientific principles.

In addition, since the conventional art learning air rocket is also formed as an integral type, there is a disadvantage that the air rocket flying in the air when the air rocket is fired at night can not be examined in detail.
