In the video, a man is seen standing in front of a white bathtub. He is holding a bottle of Pepsi and a white cotton ball. The man then proceeds to put the cotton ball into the bottle and pours it into the bathtub. The Pepsi begins to fizz and foam up, creating a large bubble that rises to the top of the bottle. The man watches as the bubble grows and eventually pops, leaving a mess of foam and liquid in the bathtub.
