The video shows a large cloud of smoke rising upwards. The smoke is thick and white, and it appears to be billowing and expanding as it ascends. The background is dark, which contrasts with the brightness of the smoke, making it stand out. There are no other objects or people visible in the video, and the focus is solely on the smoke and its movement. The smoke's shape is constantly changing, with no two frames looking exactly the same. The video does not contain any audio or additional visual effects.
