How to Make Simple Rocket Using Balloon

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.

MATERIALS REQUIRED

One long balloon
One string
One plastic straw
Electrician Tape

PROCEDURE

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.

WORKING

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.

Energy generating speed humps

In your view there may be many uses of Speed Humps like Safety, Speed limiting etc, What if i say speed humps can be also used for power generation? you heard me right using a simple setup we can effectively us speed humps for power generation, So why speed humps? After consuming non-renewable source of energy for years people are looking forward for renewable source of energy.Search of energy lead to power generation using sunlight, wind, tide etc. When talking about new source of energy people are asking for effective, renewable, maintenance less, nature friendly energy sources. When talking about energy generation using speed humps all above conditions are matching so this method can be effectively used to power street lights, traffic signals etc. BASIC FLOW CHART MATERIALS REQUIRED Rack Pinion Large Sprocket Chain Small Sprocket Flywheel Large Gear Small Gear Generator Ball Bearing RACK AND PINION GEARS: The rack and pinion used to convert between rotary and...

Six Leg Kinematic Moving Machine

Four bar linkage are the closed loop kinematic linkage , they perform a wide variety of motions with a few simple parts. This project discusses the design & fabrication of one such mechanism (Four Bar Mechanism). In this project Six Leg Kinematic movement works on Grashof’s principle which states that the sum of the length of the shortest and longest links must be less than or equal to the some of the other two links. However this condition is necessary but nor sufficient. Mechanism satisfying this condition will fall into crank-rocker mechanism, double crank mechanism and double rocker mechanism. A frame, connecting rod, crank & a lever constitute to obtain the required motion. In this project we tried to show mainly the application of simple four bar mechanism. PHOTOS & DRAWINGS APPLICATIONS It would be difficult to compete with the efficiency of a wheel on smooth hard surfaces but as condition increases rolling friction, this li...

Mechanical Spider using Klann Mechanism

The invention provides a walking device which stimulates a gait of a legged animal. The device includes a frame with spaced axial mounts, a leg, axially connected upper and lower rocker arms which limit reciprocating leg motion. The leg is driven by a connecting arm powered by a rotating crank. The position and configuration of the axial connecting sites establish a prescribed orbital path that the foot undertakes with each revolution of the crank. Both rocker arms and the crank are axially mounted to the frame. The leg has a hip joint axially connected to the upper rocker arm for limiting hip motion, a foot and a knee joint axially connected to the connecting arm. The connecting arm has three axial connecting sites, one for connecting to the knee, another to the crank, and a third connecting site defined as a centrally disposed elbow joint connecting site which connects onto the lower rocker arm and limits knee joint motion. Under power, crank rotation is transferred to the connectin...
