Why does a wooden spoon stop a pot from boiling over?

Explanation:

dry wooden spoon destabilizes the bubbles when they come into contact with its water-repelling surface. This makes the boiling water retreat. ... The wooden spoon, being considerably cooler than 100°C, thus works to break the bubbles and make the foam retreat

The wood is water repellant so it breaks the bubble making the boiling go down.
