Cannon
When we started our working on our cannon we first balanced the chemical equation which is C2H5OH + 3 O2 => 2 CO2 + 3 H2O and then we thought of a design for our cannon. We each began looking up different cannon designs and angles that we could have the cannon at. The angle we chose had to be almost perfect; if the ball went to high it wouldn’t gain hardly any distance but if the ball went to low it would have a chance of hitting the ground before its max distance. We came to the decision that cannon should be around 40 degrees so we can maximize its distance. We had to think about our design that we came up with an see if it can hold a angle around 40 degrees. We had to make some improvements to our design to hold our angle. We decide to cut a groove into one of the tennis ball container and stick the other one into it. After building I had some doubts about it but I finally came around to it that this can work.
