 This is my data...I used all of the same variables for everything except in the second flight I changed the nose cone material. It made a huge difference. When we build our rockets we are going to make our nose cone out of cardboard because it makes it cut through the air better and increases its velocity.

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 :)
