This is my research from today...there are a lot of pros and cons to the size and shape of the fins. What do you think we should use? Also in the man's video I got this info from he does not use a closed pressure chamber...we will have to modify his design because we do not have anything to weld the bottles back together. For this experiment we will need two bottles, a weight (rubber band ball), poster card (for the nose) and a scale...I can get a rubber band ball and possibly a few bottles. I can also get the poster board...could you (Addison) bring a few other bottles for different shape types? Thanks :)
Yeah no problem I can bring some other bottles. When I watched the video the man said that he liked to use plastic for the fins so maybe we could try to use those? I'm afraid that if we tried to use paper or cardboard for the fins, when we launch it the air rushing overtop of the rocket at the launch will distort our fins and cause our rocket to fall of course! Oh my that would be a tragedy! However; we'll have to figure out what fin shape will provide less drag and not add that much weight. Right now im thinking either a hexagonal shape or a triangular shape. In my research from today I concluded that if we use 3 small fins and place them near the bottom it will be the most effective and cause the least amount of drag. We can test out our theories tomorrow.
