During the last weekend we were suppose to find information about bottle rockets and post it so other people can use it as well. In the next couple weeks we are going have to make a bottle rocket stay in the air for over ten seconds. The website I found was pretty useful. It explains how it uses all three of Newton's laws. It also tells you the most effective place the center of mass should be and where the center of pressure should be. It tells you the pressure ratio that is effective and tells what kind of fins are effective. The steps are simple enough and can help everyone. Doing this was great because it only makes it easier to help us make our bottle rockets and get better grades.
