Model Rockets
Model rockets are made or assembled by hand, and propelled by a variety of means; the hobby can be quite simple, or very involved. This category will cover the information and skill levels on making and launching model rockets.

What is the difference between a multistage rocket and a single-stage rocket?
A single stage rocket consists of only a single set of rocket engines and fuel containers. This assembly is used for the entire journey. A multistage rocket consists of several sets of engines and fuel containers that are used in succession. When the fuel of one stage is spent it detaches from the rocket to get rid of the weight and the next set of engines is ignited. Multistage rockets are far more efficient at getting things into space.
of course you can.... with the technology we have now aw days we can do anything!
The model rocket rests on the center of gravity, which holds it in place. This makes sure the weight of the object is evenly distributed.Ê Another force that holds the rocket the center of pressure. All the aerodynamic forces of the rocket are centered.
What is the streamer for on a model rocket?
So that when it finishes it's flight and opens, you will see it easier by the streamer.
How can you tell if the forces are balanced once the rocket is in flight?
You should test your rocket's stability BEFORE you launch! Locate the center of gravity (CG) on your rocket and tie a long string (about 6 feet long) around the body of your rocket at the CG point. Take the other end of the string and swing it over your head around your body. If it flies straight, you're good. If it wobbles or tumbles, then you need to shift the CG more forward of the center point. If you don't know the relationship of "center of gravity" and "center point", you should read up first before you consider launching a rocket. Apogee.com is a great site to learn from. Good luck!
Are model rockets safe for children?
Yes, I would say based on my research, model rockets are safe for children. The site, http://en.wikipedia.org/wiki/Model_rocket, quotes, "Model rocketry is a safe and widespread hobby."
How does the parachute come out of the model rocket?
You must use a motor with 'retro fire' if you have a parachute. -At the apex of the flight, these motors fire a short burst into the rocket tube, and the expanding gases push the nose cone off so the parachute comes out and opens up.
How does the angle of the launch pad affect the distance of the model rocket?
Yes, it does. I never use more then about a 10 degree offset
Why do you need water in a bottle rocket?
water is needed to keep the air in until the water is expelled out.
How do you set off a model rocket without a launch set?
To set off a model rocket without a launch set, you can use a simple electrical ignition system. Connect a pair of wires to the rocket's igniter, which can be made from a safety fuse or a small electrical match. Then, use a battery or a power source to create a circuit and ignite the igniter. Ensure you're at a safe distance and follow all safety precautions when launching.
What makes a model rocket go up into the air?
rockets take off when gases are shot out of the opposite direction with great force. The gases are conctrated by being forced through a small nozzle Liquid hydrogen and liquid oxygen is the fuel.
Can you blast a rocket model in school?
It is up to the school board's rules of the school you are attending. You would most likely need permission at least from the principal, but I could easily see it allowed as long as it were done for educational purposes.
Does the shape of the nose on a rocket affect how high it goes?
If the nose is pointy, the rocket will go faster, but if the rocket's nose is flat, it will just travel slower in the lower atmosphere, the height a rocket attains depends on the efficiancy of its engines, the amount of propellant carried and the launch profile. However, for a subsonic rocket (which is what most hobby rockets are) then a curved on not a pointy one is much better. I would suggest looking it up on wikipedia.
Where can you buy a model rocket?
Several model rocket kits and engines can be purchased at any Wal-Mart or K-Mart. Toys 'R US should have them as well. For more powerful engines, visit your local hobby shop.
How does a rocket engine work?
It is not an 'engine' as such, just a formed piece of highly combustible material that burns fiercely and ejects its force through a narrow nozzle creating high thrust.
