Punching v. Fire Hose

When a fireman opens the valve of a fire hydrant, the water surges into the fire hose, and causes the hose to suddenly jerk straight and become rigid, allowing the water to flow with little resistance until it leaves the nozzle and strikes the fire. When punching an opponent, imagine that your shoulder is a hydrant. When the hydrant is turned on and forces are suddenly applied down the arm, your arm should suddenly straighten toward the target and become rigid until the forces are released into the target.
