Our rockets were the exact same except for the variable we were testing which was our fins on Will’s rocket we had fins that made the rocket spin while my fins made my rocket glide through the air to its highest possible height. After looking over all of the variables that are related to a bottle rocket we decided that fins would be the most interesting one to test. We wanted to do an original test with the fins so we decided that we would arrange the fins so the rocket would spin. All of that lead into the idea of testing spin on our rockets. Would a rocket that spins affect the height of it compared to the same rocket that does not spin. If the rocket spins then the rocket will go higher because it is screwing right through the air.
Our testing procedure went like so, we first made sure that the rockets weighed the same ( 172g) and were filled up with the same amount of water (1010ml). After making sure that the right rocket would spine and the other would not, we did this by doing trial and eare. We perserized the rockets to 50 psi and launched the rockets. We did this three times for both rockets.
Variables that we kept constant were...

We were not able to keep the size of the fins contain because to make the rocket spin the fins had to be a different shape and size. Although the fins were different sizes we made sure that the rockets still weighed the same.
