Activity-Bottle Rocket

There are many approaches to this problem. The most common method is creating a separate air chamber using an empty soda bottle. A weight drops on this bottle to exert air pressure. This air pressure is then used to launch a projectile, adjusting the height of the weight as needed. Although easy, this method is too imprecise and will yield inaccurate results. To begin, it is needed to learn about how air pressure is created and the best way to achieve it. After

When I first started building my bottle rocket, I had two water bottles. The one I used for my bottom, I had to cut the top of it so the top piece could fit in it. Then I had to get some duct tape, and rapped it around the side where it was cut. Then I cut out four triangles but only used three. I got a hot glue gun and put it onto the triangle and placed it on the bottom part of the bottle. Then I painted it with turquois paint.

A rocket is a cylindrical projectile that can be propelled to a great height or distance by the combustion of its contents. Robert Hutchings Goddard, was the first to create a liquid fueled rocket in 1926. Robert was about 44 years old when he invented the first liquid fueled rocket. Roberts rocket reached an altitude of 41 feet at about 60 mph and lasted about 2 seconds. The rocket landed approximately 184 feet away from the blast off place. The rocket was about 10 feet tall, made out of thin pipes; it was fueled by liquid oxygen and gasoline. Chinese were the first to create rockets for military in the 13th Century. They made the rockets out of gunpowder; probably built firework rockets before the rockets for wars. The

Newton's first law is often called, “The law of inertia.” This law states how an object in motion tends to say in motion unless something interacts upon it. How does this form a connection to water rockets? Well, the answer is quite complex. It includes a sequential order of how a water rocket works, and when the First law of motion ties into it. When you launch a rocket, you don’t put it on the ground and tell it to, “fly.”

Perform the same experiment again. This time the empty gallon goes up even faster than the first time and the full gallon comes down quicker. Discuss how the changes in mass effected the acceleration

A compressor operates on the principle of Boyle’s Law – reducing the volume increases the pressure. The air is compressed in stages.

My rocket is made out of two plastic bottles (preferably two liter bottles but it also works with other types of bottles) that are cut to fit together with the cap duct

Today’s rockets are used for shipping satellites and other equipment up into space. But let’s go back in time to when rockets weren’t used for that big of a task. The first invention with the properties of a rocket was a wooden bird made by a man named Aulus Gellius. It was invented sometime in the late 400’s. People were amazed by the flying pigeon made of wood. The pigeon flew with a principle called the action-reaction principle. Which was not a scientific law until the late 1700’s. About 300 years later another man made a rocket type of rocket invention called the aeolipile. It too used steam as a propulsive gas. The Chinese also began testing out tubes filled with gunpowder. Not long after they went through and attached bamboo

The device will have a piston motor in it. First, open the inlet and close the outlet, let the piston goes up, the pressure

He has a high powered motor stuck to the back of his body. This motor propels his through the water in the quietest and smoothest manner possible. He makes an “S” and moves it

It works pretty much like the ramjet engine. It takes in air through air inlet but instead of slowing it down to subsonic speed, it compresses the air to a supersonic speed. After compression, the air is combusted but instead of using normal jet fuel like other engine, the scramjet engine uses hydrogen for combustion. After combustion, the air is let out through the exhaust. The increase in air's temperature and pressure, causes acceleration in the aircraft and thrusts it forward.

and a set of forces and moments take place initially to return the aircraft to its original

There are 4 main forces, drag, lift, thrust and weight. Lift is the force that counters weight. It occurs when the pressure of the object below the object is greater than the pressure above it. The second force, thrust, counters drag. It propels the object in a given direction and can be provided by turbofans, turboprops, propfans, etc. on an airplane, but can also be provided for an arrow by the bowstring. Weight counters lift and varies with mass. The greater the mass, the greater the force of weight is. The last force, drag, counters thrust. The air particles stick to the object, creating friction and heat which slows the object. Drag occurs everywhere where there is a fluid, with almost (practically) no effect in space.

First check your closet/ house for anything you might want to do with your bottle or bottles. It does not matter if you do not later you do not use all the materials you initial gathered. After gather your material locate the perfected bottle or even bottles. Most used bottles are mason jars and wine bottles, however I have found out that beer bottle work perfectly find, but I used something called a marble soda bottle. My other materials include glue and green and red paint and red and green glitter. If you do not have all you want to make your bottles you will have to trek the horrors of…
