With the combined influences of heat and water, the starch thickens as it rises to the surface, creating an active agent at the top of the water which blocks air from escaping. Because it contains more air, the volume of water then expands, rising to the point of boiling over.
Why do pots boil over with lids?
Putting a lid on a pot of boiling water will increase the vapor pressure above the surface of the water, causing the water to boil more vigorously and the bubbles to persist longer, especially since the noodles have released starch and protein into the water and increased its surface tension.

Does water boil faster with salt?
Adding salt to water is going to do two things to water’s physical properties: it will raise the boiling point and it will lower the specific heat. These two changes actually work against each other. Raising the boiling point will make the water boil slower.
Does oil stop water from boiling over?
According to Easton, olive oil sits on top of the boiling water and interrupts the surface tension, therefore preventing the water from foaming up and boiling over the pot.
