In the video, a person is seen kneeling on the floor with two buckets in front of them. The person picks up a potato and dips it into one of the buckets, which is filled with water. After a few seconds, the person takes the potato out of the water and places it into the other bucket, which is filled with a different substance. The person then rubs the potato against the substance in the bucket, creating a foam. The person repeats this process several times, dipping the potato into the water and then into the substance. The video does not provide any information about the purpose of this activity or the substance being used.
