Scientific revelation:

 Usually we have played with balloons, when we blow the balloon full air, mouth down, let go will hear the sound of air from inside the balloon, at the same time see the balloon up? But do you know why the balloon is going up? Let's make an interesting balloon plane.

Experimental purpose:

1. Know about balloon helicopters and their construction 
2. Cultivate children's ability of observation and experiment as well as hands-on operation

Experimental cognition:

How it works: jet planes use aerodynamic principles. The contractive force of the balloon is used to cause the air flow to rotate the propeller and generate power, so as to drive the whole toy to make a balanced upward flight. At the same time, part of the airflow is diverted to the sound device, which will also make a pleasant sound, which is very attractive.
Aerodynamics: the branch of fluid mechanics that deals with the forces produced by moving objects through air or other gases.

Scientific production:

1. Prepare to know the experimental equipment balloon, air nozzle, interface and propeller
2. Install the propeller to be connected with the interface; And put a balloon on a balloon;
3. Blow up the balloon and hold the sealing of the balloon with your hands to keep the air from flowing out;
4. Hold the balloon in your hand and connect the air nozzle to the port where the propeller is mounted.
5. Hold the balloon helicopter until it is parallel to the line of sight and let it fly.
Tip: hold the balloon by hand and connect the interface, do not let the air leak out of the balloon, so as not to affect the effect of balloon helicopter flight.

Principles of science:

Principle of aerodynamics.
Balloons and propeller interfaces are connected by a gas nozzle, interface and three into a certain Angle, horizontal propeller blade and propeller Ye Zhongkong, for air circulation channel, and a vent, caused the balloon contraction force and air flow within the propeller to vent discharge and power generation, can cause three propeller blade rotation, prompting the aircraft flying in the rotation, and some of the air circulation to the whistle, make jet beautiful voice on the rise.

Scientific development:

Aerodynamics is widely used in aerospace, such as jets and satellites. In addition to the above development of aerodynamics driven by the development of aerospace industry, since the 1960s, due to the development of transportation, transportation, construction, meteorology, environmental protection and energy utilization and other aspects.

   Before assembling, please check whether the circuit is smooth, whether the circuit fittings are complete, and whether all contact points are in good contact. Be careful not to get the glue on the clothes or the skin during assembly. Spare parts should be put in the place where the younger brother and sister can't get, so as not to swallow the parts by mistake! Don't put it on your head, lest it fall and hurt you!
