In the video, a person is seen holding a clear ice cube in their hand. The ice cube appears to be made of water that has been boiled, as indicated by the word "Boiled" that appears on the screen. The person then places the ice cube on a brown surface, and another ice cube is shown next to it. The second ice cube is labeled "Un-boiled" and is placed on the same surface. The person then picks up the "Un-boiled" ice cube and compares it to the "Boiled" ice cube, showing the difference in clarity and texture.
