1. Pass the rope through the straw.

2. Holding a rope in the house. Stick two pieces of tape on the straw.

3. Inflate the balloon with a pump.

4. Grab the neck of the balloon and stick it on the adhesive tape.

Let go of the balloon and it rushed out at high speed along the rope. An air jet from the neck of the balloon pushes it forward.

Principle:

Same principle as jet engine.

Gas propulsion is Isaac newton (Isaac

Practical application of Newton's third law of motion. ? The law is expressed as: "Every force acting on an object has a reaction force with the opposite direction and the same size." As far as aircraft propulsion is concerned, "object" is the air that is accelerated when passing through the engine. The force required to generate this acceleration has equal and opposite reaction forces acting on the device that generates this acceleration. Jet engines generate thrust in a way similar to an engine/propeller combination. Both of them push the aircraft by pushing a large amount of gas backward, one is in the form of a relatively low-speed large amount of air slipstream, and the other is in the form of a very high-speed gas jet.
