Our design was built to optimally maximize pressure using a double-barrel model. This built up more pressure in the smaller chamber as to launch the Nerf ball further, using more kinetic energy. This dealt with Boyle's law, regarding volume and pressure. We didn't take into account Gay-Lusaac's law, dealing with temperature as well, which is most likely why our cannons didn't fire. To create a better environment where the cannons would have a better chance of firing, we should have chosen a warmer day. The cold air decreased the pressure within our cannons, making it impossible for them to build up the energy to propel the Nerf ball forward.
