In the video, a man is seen standing in front of a black curtain. He is wearing a purple shirt and a black cap. The man is holding a string in his hand and is talking to the camera. He then proceeds to pull the string upwards and downwards, creating a wave-like motion in the curtain. The man continues to talk while manipulating the curtain with the string. The video is shot in a vertical format, and the lighting is dim. The man's facial expressions and body language suggest that he is engaging with the audience and demonstrating something.
