My group constructed our cannon so that we decrease the volume so that the pressure was greater which is what Boyle’s law states. We did this by folding the plastic onto itself and doubling up the cans on top of each other. We also tried making our cannon more successful by choosing a 35 degree angle because we wanted our cannon to go further instead of higher so we chose something slightly under 45 degrees. When it came down to firing the cannon, ours didn’t fire as well as all the other groups because Gay Lussac’s law states that with a colder temperature, there is less pressure and it was cold that day so there wasn’t enough of a pressure to fire the cannon. Working in a group helped us to put all of our ideas into the cannon so that the cannon was extra good and it also helped speed up the process.
