My partner and I started creating our bottle rocket. Our first trial had three wings, around the same size and position but not quite, and taped together at the top to try and trap air when it fell down. We went on the hope that the rocket would fall back down and the air that could be caught in the wings as a make shift parachute (at that time we didn't have a cone or a chute to work with). It didn't end up working. At all.
Our next design had four identical wings (taped in duct tape in case it rained) and had a rock taped to the top to balance the rocket out. We added a cone to the top (courtesy of Jasmine and her cone selling business) and folded up a plastic bag parachute inside of it. We also added another cup or so of water. The launch worked out well, just making five seconds.
