In this video, we see a man standing in front of a chalkboard filled with writing. He is holding a shoe in one hand and a hairdryer in the other. The man appears to be using the hairdryer to heat up the shoe, possibly to soften or melt something on it. The chalkboard behind him has various mathematical equations and diagrams written on it, suggesting that the setting might be a classroom or a lab. The man is wearing a sweater and seems to be focused on the task at hand. The lighting in the room is bright, and the colors in the video are quite muted.
