Bosuns Whistle Necklace

The boatswain’s call, pipe, or bosun’s whistle is a pipe or a non-diaphragm type whistle used on naval ships by a boatswain. The pipe consists of a narrow tube (the gun) that directs air over a metal sphere (the buoy) with a hole in the top. The player opens and closes the hand over the hole to change the pitch. The ‘shackle’ is connected to wave and fish-inspired beads. Piping hot we say!
