Hypothesis

I think that our cannon will be especially successful in launching. We used a double-chamber design to maximize pressure and propel the Nerf ball further. We used a 1:1.5 ratio for the two chambers. The smaller chamber was the one in which the reaction took place, and the longer one was where the Nerf ball was held.

After-firing reflection: We weren't able to tell if our cannon would have shot the farthest, because none of our cannons shot. We determined that the low temperature was an independent variable and that decreased the pressure in each of our cannons, not providing enough energy to launch the Nerf ball.
