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. Anyone can make their own water rocket by using simple household material like plastic bottles, electrical tape, polythene bags etc. It is an interesting project and explains the working and aerodynamics of a rocket which uses pressurized air and water as fuel.
Material Required to make water rocket
To make a water rocket, you will need following material,
To make a water rocket, 2 carbonated bottles will be required: one is for body of water rocket and other for skirt of water rocket. Fins will be attached to the skirt. The advantage of these bottles is that they do not burst under high air pressure. Bottles with less designing and curves are used to minimize weak points in bottles.
Fins of water rocket are made with the help plastic file. One file is enough to make fins. They help rocket in flight by cutting the air around. Do not use cardboard, card sheets or paper fins as they will get wet, bend or tear apart by water.
Shock absorber is made with the help of polythene bags which will save the rocket from being damage when it hits the ground. It is filled in the head of the rocket.
- A Pair Of Scissor.
- Electrical Tape.
- A Ruler.
Steps to make Water Rocket
Water rocket construction consist of 3 parts. The parts are Nose cone, skirt and fins. The making of each part, its significance and importanc 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
The Skirt gives the proper shape to the rocket and we will attach the fins on it. Another carbonated bottle or plastic file is use for making it. Divide the circumference into 4 equal parts and attach fins 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.
