So I figured I’d, write about why our water bottle rocket failed so miserably on arts fest. Our goal was to use parachutes that would cause our rocket to slowly descend to the ground. Instead of using just one, we figured using two would slow our rockets fall even more. In theory this would have worked fine, however when our rocket reached its maximum height and the nose cone fell off exposing the parachutes, instead of fully opening, the two chutes tangled together and didn’t fully open. The unopened parachutes did very little too slow the decent, causing the rocket to fall very quickly back to the ground. Perhaps sticking to one parachute, or attaching the string of the second parachute to the top of the other would have been a better plan.
