Its existence encourages people to sing in the shower because surfaces there are reflective and at the right distance for it to occur at vocal frequencies.

Microwaves create it in water, something that is very easy because H2O has three distinct rotational modes and three more vibrational modes. It is more familiar for the sound in a seashell, actually an increase of background noises. For ten points, name this type of vibrational amplification caused by an external force that is at the same frequency as an object's natural vibration.
