In the end, the ideal amount of water to Alka-Seltzer was 4 ML to ⅓ a tablet. When we used less water (Independant Variable) it gave the canister more space for the pressure to build up, resulting in longer flight (Dependent Variable). This goes for when I tried to launch a canister with 35 ML of water and ¼ a tablet of Alka-Seltzer. The canister was ¾ filled which wasn’t enough space and so it failed to launch. When I tried to put higher amounts of water, the canister would leak. I accept my original hypothesis because my measurements were close and I knew that I needed enough space inside of the canister in order for it to launch. To improve results in the future, I would be more precise with the amounts of water and Alka-Seltzer I use because
