This cannon ( made up ) is a battery operated and can be lined up in a long line, the motor loads the hinge so it builds up tons of potential energy, the cannon is connected to a long string so it will get most of the energy. When any enemy guy or group, the person controlling the cannon releases the motor throwing the loaded hinge shooting the ball. #army #ball #cannon #nick #sketchy_physics #sketchycat #sketchyphysics #war #weapon
