How does a model rocket work?
The typical path for this type of hobby is you first make a rocket out of a cardboard tube and add fins (either balsa wood or plastic) then attach a parachute and nosecone. Into this rocket tube you install a thing called an engine. It is what creates the propulsion for launch and it is a cylindrical object about the size and shape of a roll of pennies and it contains an ignitable dry propellant. You insert this engine into the bottom of the rocket and when it is fired it propels the rocket into sky. After a certain period of time (usually 4-6 seconds) the propulsion stops and a secondary charge goes off the other end of the engine. This causes the nose cone to blow off the rocket and the parachute to deploy “which safely carries your rocket back to the ground so you can use it again. The engine however, is spent and to launch the rocket again you would install another engine. These engines cost from 2 to 3 dollars each. How do you fire off the rocket? You fire off the rocket engine by
