If it has the holes already just put the fins in and screw them in from the other side.
I am not sure of the exact year, but the Chinese had rockets years before anyone in the west has thought of them. Since they had gunpowder, it was a natural extension to put gunpowder in a cylinder of some kind. Most likely bamboo, and then light it. Fireworks were invented.
Rockets, and then they just push them out the rocket door, and they adjust them with little rockets into orbit

easy! get some balsa wood and a modeling knife!and cut out a simple shape!balsa wood is ok because it is light in weight, however, if your rocket has a crash landing the fins will not likely survive. I suggest something a bit more sturdy. on some rockets i have used chucks of CDs as fin material (they're harder to snap than you would think) i would also suggest arrow glue ( like the glue for archery arrows) as an adhesive for fins shape? i would check out this web site. the fin designs are not difficult to create and the shape is backed up by the Reynolds number don't know if you know any thing about that http://www.apogeerockets.com/technical_publication_16.asp.best of luck! :]
because they don't need anymore than three fins to keep them on straight course
Rockets have sent unmanned spacecraft to mars and Jupiter. Satellites put in orbit by rockets beam back information about earth's atmosphere and weather.
