Rockets have been around for hundreds of years carrying out different purposes. They can be used for weaponry, fireworks, ejection seats, launching vehicles such as spacecrafts for artificial satellites, human space flight and exploration. The earliest design of rocket was made in China and India for showing fireworks. The word ‘rocket’ is commonly used to denote three different forms of objects:

1. A flying vehicle used by astronauts to fly into space for discovery reasons.

2. A weapon that is fired from tanks toward an aircraft.

3. A replica of any of the above two objects that is used to practice or comprehend air launching or to push fireworks into the air.

The only distinction between the rocket used to propel spacecraft into space and the one that is used as missile is how they are constructed. Spacecraft are built with a durable, short thrust that will get them into space as this is their primary aim. The rocket missile must be maintained to ensure that staying power is kept at the requisite standard. Despite the kind of rocket, they all use a related chemical reaction to shoot the object into the air. The chemical used to launch rockets may be gasoline, liquid oxygen or liquid hydrogen.

Making a rocket can be enjoyable particularly if you are working with children or if you just want to do something inventive. You have two options to choose from – either making one from scratch or buying a kit to fit together. Your homemade rocket may not fly as high as one that you can purchase but it is inexpensive and the project is entertaining. It is crucial when constructing a rocket from scratch to trace a simple plan first. The guidelines below will help you to create one from scratch.

How To Build A Rocket

Required Materials:

Plastic Cylinder object (soda bottle is an excellent selection)

Nose cone



Wood glue

Plastic cement

Launch pad

Engine mount


Sand paper

Cotton bud



Required Tools:


Small paintbrush

Ignition system


Craft knife


1. Use the pencil to trace the design on a piece of paper. It must have a cylindrical body, nose cone, three fins, and an engine.

2. Affix the nose cone to the cylindrical body and attach the parachute to the rear of the nose cone using plastic cement.

3. To make the fins, sketch the plan with a pencil on paper then cut out the object from the balsawood with the craft knife. Use sand paper to sand the fins to make them smooth.

4. Use rubber cement to firmly connect the fins to the soda bottle or your selection of cylindrical object.

5. Affix the engine mount to the object. It must be placed into the bottom of the rocket underneath the fins. In order to set up correctly, take a cotton bud and apply glue to the exterior of the engine mount. Slide it beneath the fins in the bottom of the rocket. The glue should hold it into place.

6. Paint your rocket with several light coats for a more appealing appearance. So long as the paint is totally dried, you can launch your rocket.


It is crucial to smooth the fins as air travels easily over smooth fins than rough ones.

When launching your rocket, be certain you do so in open spaces away from people, animals, vehicle and electricity cables. This will lessen the hazard of injury or damage.

You can try working with more fins or different designs because the fins are very vital in influencing the way a rocket flies through the air.
