In the video, a person is seen pouring milk into a pot of boiling water. The milk is being poured from a carton, and the pot is placed on a stove. The person is careful not to spill any of the milk as they pour it into the pot. The boiling water causes the milk to bubble and froth as it is added. The person then stirs the mixture with a spoon, ensuring that the milk is well-combined with the water. The video ends with the person continuing to stir the mixture in the pot.
