A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forward simply by throwing their exhaust backwards extremely fast.
Rockets are relatively lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency. Rockets are not reliant on the atmosphere and work very well in space. We don’t need more technical details for making our simple rocket, leave all it behind & lets see how to make a simple rocket using balloon.
- One long balloon
- One string
- One plastic straw
- Electrician Tape
- Tie one end of string to any where you want your rocket to launch (it can be a chair, window bars or something you find suitable).
- Now insert the straw through other side of the straw.
- Now blow balloon as much as you can (don’t tie it, hold it with your hands).
- Tie balloon with straw using electrician tape or some other things you have.
- After completing above steps it will look like picture shown below.
- Now its time to launch, just release your hand from balloon mouth & see your rocket flying.
Wondering how it works? here is the secret for you. When you release your hand air inside balloon will come resulting a force to move balloon forward. The created force is known as thrust. Thrust can be simply defines as the force created by energy. Thrust is produced in real rockets also, the only difference is here thrust is created by the air coming out of the balloon but in real rockets thrust is created by the combustion of fuels.
