In the video, a young boy is sitting on a couch and talking to the camera. He then proceeds to show the camera how to crack his knuckles. He starts by cracking his thumb, then moves on to cracking his fingers one by one. He cracks each finger individually, starting with his index finger, then his middle finger, ring finger, and finally his pinky finger. After cracking all his fingers, he cracks his wrists by moving his arms back and forth. Throughout the video, the boy is smiling and seems to be enjoying himself.
