Design and Process Reasoning for Cannon Structure
1. In the cannon blog project we used two empty tennis ball containers, 18 inches of tape and scissors. Our team decided to create our cannon by cutting one tennis ball container in half and using it to support the other container.
2. We trimmed each tennis ball tube to the desired shape, using the scissors, following the basic drawing of our design.
3. After each piece was cut, the cannon was assembled and held together by one person while other people measured the tape (we could only use 18 inches) to hold the pieces permanently in place.
4. When we put everything in place, we each checked the cannon for any visible problems before using the scissors to poke a hole in the back of the barrel for the wood splint that will be used to light the cannon.
We chose to make the cannon to make the cannon a 45° angle, because we found through mathematical research that a 45° degree angle will give us the farthest horizontal projectile distance. We put the front support to stabilize the cannons 45° angle. It also will prevent the cannon from jerking forward as a result of thrust after the explosion. .We put the back support on the cannon to give the cannon more elevation and to prevent the cannon falling backward during firing.
Difficulties:
The only issue we really had with the construction of our cannon would have to be finding the right angels to put the tennis ball containers and the angles to place the tape. In theend, we put a lot of effort into our cannon.
Chemistry Component
Combustion Reaction of Ethanol and Oxygen
C2H5OH + O2 => CO2 + H2O
To balance your chemical equation, you have insert coefficients before the chemical formulas until there is a balanced number of each element.
C2H5OH + 3 O2 => 2 CO2 + 3 H2O

C2H5OH + 3 O2 => 2 CO2 + 3 H2O
We're not completely sure if our design plan will launch because according to Gay- Lussac's Law, temperature and pressure are directly related meaning if we were to shoot the cannon in cold weather, the pressure buildup would be significantly lesser than if we were to shoot it on a warmer day. If everything goes well and the universe is on our side, the sun will be shining and heating it up outside on the day of the launch. :)
