During heating some water gets converted into water vapour. The water vapour being lighter, rises up. … As the milk is heated further, the water vapour expands and thick foam is produced on top. Finally, the trapped vapour lifts the layer of cream up, quite like a hot air balloon, and finally bursts through this layer.
Why does milk explode while boiling?
When milk is heated, the fat which is lighter than water is collected on the surface along with certain protein in the form of a layer called cream. … When milk is heated further, the water vapour expands, pressure builds up and lifts the creamy layer up and thus the milk spills out.
How do you boil milk without overflowing?

What happens when milk boils over?
As milk heats, the water in its structure starts evaporating from the surface. This concentrates the remaining fat and proteins into a thicker layer at the top of the pot. This layer eventually becomes so thick that water vapor rising through the milk can’t break through very easily and gets trapped.

Is curdled milk safe to drink?
