A rod of length 1.2 m and mass 6.0 kg is identified as a pendulum vertically at one of its ends. A handgun of mass 0.950 kg is attached to the other end, with the loop oriented horizontally. The weapon has a Bluetooth control so that a bullet can be fired remotely with a smartphone. In a video made with a high-speed camera, after firing a 9.0 g bullet, one can even see the rod swinging upwards, with the lower end of the rod reaching a maximum height difference of 5 cm compared to the vertical equilibrium position.
