Abstract Bottle rockets, people see them as middle school science projects where kids have fun and build little rockets. Actually there is a lot behind bottle rockets, it’s more than just throw some plastic bottle together and glue some wings to it and fly it. The researcher chose this topic because in his class they are doing the bottle rocket project and he wanted to find out which rocket was more efficient for hang time. So the experimenter built some rockets and launched them and gathered the results. In this paper there is some history of rocketry which the researcher used to design his rockets. The results are also contained in this paper; they show how different dimensions of water rockets affect its hang time. The way the researcher built the rockets was fairly simple he first used a 2-liter bottle as the base, then he cut another bottle in half and taped it to the bottom of the base bottle, after he attached a plastic cup to the half bottle, and finally he taped the top half of a small Coke bottle. After launching and gathering his data he came to the conclusion that his hypothesis was right long rockets with medium size fins preformed the best and had and average hang time of 7.16 sec. Other rockets performed well but they did not have the greatest hang time of all the launches. The conditions were equal for all rockets so the hang time was not affected by other variables.
