In the video, a man is seen holding a shirt in his hands. He is wearing a white lab coat and glasses, and he appears to be conducting some sort of experiment or test on the shirt. The shirt is gray and has the word "GUESS" written on it in colorful letters. The man is using a small white device to apply a substance to the shirt, and he is carefully rubbing it in with his fingers. The background is a brick wall, and there is a beaker with a yellow liquid on a shelf behind him.
