Understanding Hard-Boiled Eggs

The video explores the differences between raw and hard-boiled eggs, focusing on how boiling changes the egg's internal structure. It explains that proteins in eggs unfold and stick together when heated, making the egg solid. The video also discusses the effects of cooling and the concept of soft-boiled eggs. Viewers are encouraged to experiment with cooking eggs to observe different textures.
