In the video, a person is holding a green object in their left hand and a black and gray device in their right hand. The device has a small screen that displays the temperature of the object. The person moves the device around the object, and the temperature readings change accordingly. The object appears to be a small, green, oval-shaped object, possibly a piece of fruit or vegetable. The device is likely a thermometer or infrared thermometer used to measure the temperature of the object. The person's actions suggest that they are testing the temperature of the object from different angles and distances.
