How to Make a Water Rocket Step By Step Instructions
Introduction to Water Rocket
To make water rocket is one of the practical demonstration of construction and working of rockets. It can be made by the simple household material like plastic bottles, electrical tape, polythene bags etc. It is an interesting project to explain the working and aerodynamics of a rocket in which pressurized air and water are used as fuel of the rocket.
Material Required to make water rocket
To make water rocket, following materials are required:
2 carbonated bottles are required to make water rocket: one is for body of water rocket and other for skirt of water rocket to which fins will be attached. The carbonated bottles are recommended because they do not burst and can bear high air pressure. It should be kept in mind that bottles with less designing and curves must be used to minimize weak points in bottles.
One plastic file is needed to make four fins of water rocket; fins help the rocket in flight by cutting the air around. As water is used as fuel, cardboard or paper fins must not be used as they get wet, bend or tear apart.
Polythene bags are served as shock absorber when rocket return to the ground. It is filled in the head of the rocket so that it may not get damaged.
- A Pair Of Scissor.
- Electrical Tape.
- A Ruler.
Steps to make Water Rocket
The construction can be divided into 3 parts to make water rocket. The parts are Nose cone, skirt and fins. Making of each part and its significance is described as under:
Making Of Nose Cone
Nose cone is one of the important part in making of water rocket. It helps in flight of the rocket due to its aerodynamic shape by minimizing air drag or resistance which opposes the rocket's motion. The polythene bags filled in the cone work as shock absorber when it returns to the ground
Making Of Skirt
Skirt is made to give the rocket proper shape and space to attach the fins on it. It can be made by using another carbonated bottle or by using plastic file. It must be equally divided into 4 parts so that 4 wings can attached to it with equal spacing.
Making of fins
The fins are the most important part of water rocket that are used for controlling the direction and minimizing the air drag around the rocket while flying. It also provides stability to the rocket to keep flying without being tumbled or wobbled in the air.
