Kiama Blowhole

What is a blowhole? (Excerpts from Wikipedia)

A blowhole is formed as caves grow landwards and upwards into vertical shafts and expose themselves towards the surface , which can result in quite spectacular blasts of water from the top of the blowhole if the geometry of the cave and blowhole and state of the weather are appropriate. The Kiama Blowhole (Kiama, New South Wales, Australia) is believed to be the world's largest blowhole.
