In the video, a man is seen holding a flashlight. He begins by unscrewing the top of the flashlight, revealing the battery compartment. He then removes the battery and unscrews the bottom of the flashlight, showing the bulb. The man then unscrews the side of the flashlight, exposing the internal components. He then screws the side back into place, and the bottom of the flashlight, before finally screwing the top back on.
