mbustion, aids in production, such as solvents, and lubricants. However, some of these functions tend to overlap, so for simplicitys sake, we have included here only the commonly used materials. The burning speed of a firework mixture is controlled by a variety of factors, the major three being particle size, temperature, and pressure. Firework compositions are usually mixed in a special type of a structure. It is standard procedure to use several buildings, one for sulphur mixtures, for chlorate compositions, another for ammonium perchlorate and finally, one for magnesium. All of these types of fireworks require some type of container. In the past, tubes of paper and occationally wood has been utilized- nonetheless, paper remains the most popular and the cost effective. Several exceptions are signal flares which are usually pressed into either steel plastic, or aluminum tubes.There are very many types of visual and audio effects for fireworks. As this is relatively unimportant to our research we will only briefly list them: Stars, colored fires, Bengals, lances, Portfires, Torches, Roman candles, comets, Mines, Noisemakers, Rockets, Drivers, saxons, tourbillions, shells, Gerbs, fountains, rains, squibs, Cones, Pinwheels, Crackers, and Smoke bombs are the better known types. Indoor Fireworks and Professional pyrotechnic displays will be ignored since they operate on somewhat different principals. They also require more professional handling. (obviously.)For our experiment we have decided to focus solely on rockets, because of their relative simplicity and since we only wanted to use basic trigonometry in our experiments as Ailia is only in Algebra 2 Trigonometry, and Marla is in Advanced Pre calculus. For the experiment itself, we have found several equations which we are considering applying. The first equation we came across is how to calculate the size of fireworks, which is size (feet)= 6pi (time in seconds) *angle in degr...
