In this video, a man is seen standing in a kitchen, holding a cocktail shaker. He is wearing a black and white shirt and has a watch on his left wrist. The man is demonstrating how to properly shake a cocktail. He starts by holding the shaker with both hands, then he places his right hand on the bottom of the shaker and his left hand on the top. He then shakes the shaker vigorously, moving it back and forth in a circular motion. After a few seconds, he stops shaking and sets the shaker down on the counter. The kitchen in the background has wooden cabinets and a few books on a shelf.
