If you want a buzzer that really floats - a suspender buzzer, just tie
in a few bits of C-D-C at the eye to make it float.

A small ball of booby foam works too. :-)

How do you attach it though?

Suggestion! Wrap the little polystyrene ball on a piece of condom. It
makes the bead waterproof. Much better than the old idea of nylon
stocking.
