Best Cannon

The best cannon would be sturdy and powerful enough to launch an object over a great distance. The cannon should be made with a long tube "neck" to get the greatest amount of distance. The tube should also be narrow so that when the propane is set on fire, it will push the object farther. The angle at which the tube is placed is also important. If it is parallel with the ground, the object will not go very far. At, for example 45 degrees, the object will go much farther. "With every reaction, there is an equal, opposite reaction". Therefore if the cannon has a lot of firepower, it should be constructed to withstand the opposite reaction.
