How to Build a Rocket? no comments
Rockets have been around for hundreds of years carrying out various purposes. They can be used for weaponry, fireworks, ejection seats, launching vehicles like spacecrafts for artificial satellites, human space flight and discovery. The first version of rocket was made in China and India for showing fireworks. The word ‘rocket’ is widely used to refer to three different types 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 airplane.
3. A replica of any of the above two objects that is used to practice or comprehend air launching or to force fireworks into the air.
The only difference between the rocket used to push spacecraft into space and the type that is used as weapon is how they are built. Spacecraft are constructed with a sturdy, short thrust that will get them into space since this is their primary aim. The rocket missile must be maintained to make sure that staying power is kept at the requisite standard. Despite the kind of rocket, they all use a similar chemical reaction to release the object into the sky. The chemical used to set off rockets may be gasoline, liquid oxygen or liquid hydrogen.
Making a rocket can be enjoyable particularly if you are working with kids or if you just want to do something creative. You have two options to select from – either building one from scratch or buying a kit to fit together. Your domestic rocket may not fly as high as one that you can buy but it is cheaper and the project is entertaining. It is crucial when building a rocket from scratch to draw out a simple plan first. The directions below will help you to create one from scratch.
Required Materials:
Plastic Cylinder object (soda bottle is a great selection)
Nose cone
Fins
Balsawood
Wood glue
Plastic cement
Launch pad
Engine mount
Paper
Sand paper
Cotton bud
Paint
Parachute
Required Tools:
Engine
Small paintbrush
Ignition system
Pencil
Craft knife
Instructions:
1. Use the pencil to sketch the design on a piece of paper. It must have a cylindrical body, nose cone, three fins, and an engine.
2. Connect the nose cone to the cylindrical body and connect the parachute to the back of the nose cone with plastic cement.
3. To make the fins, draw 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 attach the fins to the soda bottle or your selection of cylindrical object.
5. Connect the engine mount to the object. It should be placed into the bottom of the rocket underneath the fins. In order to set up correctly, take a cotton bud and smear glue to the outside 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 look. Providing the paint is totally dried, you can launch your rocket.
Tips:
It is important to sand the fins as air travels easily over smooth fins than rough ones.
When discharging your rocket, ensure you do so in open spaces away from people, animals, vehicle and power lines. This will lessen the risk of wounding or damage.
You can try working with more fins or various designs because the fins are very vital in influencing the way a rocket flies through the air.

How to Read a Tape Measure no comments
A measuring tape is a instrument used to take the dimensions of an object or area. Tape measures come in different sizes and lengths ranging from smaller sizes of three feet or below to over one hundred feet in length. Despite the length of the tape measure being used you will typically find them in two kinds that is METRIC or IMPERIAL. The decision is yours to make for either one however, most likely the decision will be influenced by what you are measuring or by the country you dwell in.

Tape Measure
Required Material
Area or surface to be measured

Usage just requires you to draw out the tape and measure what you wish and then release for it to auto-retract or roll it back up by hand depending on which type you are using. If it is an imperial or metric tape measure there is no difficulty reading the primary numbers, however, there may be some difficulty reading the notches used for measurements in between the numbered measurements. To distinguish between the two, imperial is measured in inches and feet while metric is measured in millimeters and centimeters.
Imperial tape measures are in arrangement from one inch to the maximum length of the tape with notches between every number signifying one-sixteenth of an inch. An easy technique to read the notches is to think of the measurements out of sixteen at all times and then divide the number by two. So counting the notches at the beginning of the tape measure we have zero, then one-sixteenth of an inch, then two-sixteenth and so on until you get sixteen-sixteenth, where you would either incessantly divide by two until you have one remaining. Or divide the upper sixteen by the bottom since they are multiples of two.
Therefore reading all the notches from zero to one inch you would have 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1. Every 12 inches you ascned on an imperial tape measure you will probably see the quantity of feet including the number of inches that you have measured. Since this has been commonly standardized but might not be present in all brands of tape measures.
The metric tape measure is a little simpler to read than the imperial tape measure due to the fact that the metric system is made to have all numbers divisible by 10. A contrast would be that the imperial uses inches and segments of an inch and feet; segments of an inch are divided into sixteen, and then twelve inches total one foot.
With metric 10 millimeters make one centimeter, and then 100 centimeters equal a meter; all numbers are divisible by 10 and the notches on a metric tape measure between 0 and 10 as opposed to 16. This means you can simply check for the measurement between zero and one centimeter by counting 0.1, 0.2, 0.3 etc until 0.9 and lastly 1.0 centimeters. Any number thereafter would go on 1.1, 1.2 etc until 2.0 centimeters, and the trend would go on along the total length of the tape measure.
Tip
The imperial and metric regulations are completely dissimilar, and although in some instances you may be able to convert between the two it is extremely inadvisable. Persons in the auto-mechanics field may inform you that you may be able to find an imperial measurement which equals a metric measurement and vice-versa. But they will additionally tell you that the tools used may not match properly as a result of combining the two standards. For best outcomes you ought to keep to one standard and if you are following a guide in a book or online use the prescribed measurements and standard.
