Why does water just creates bubbles as it boils while other liquid like milk raises as it boils?

Question

Usually when I am boiling something like milk or tea, i have to keep looking at it, in order to not let the liquid spill out of the pan while in case of water I don’t have to worry about that. Water will just create bubbles as it boils, it won’t spill out of the pan, it won’t even raise a bit. Why is that?

Why are you boiling tea? Once the water reaches boiling point remove the energy input.
