This whistling spinning top is a fun toy to entertain the kids or explain some scientific behaviour of sound waves. It is wound up on the axis of the spinning top and can be launched by pulling the wire. Depending on the launch speed it makes a somewhat soft whistling noise, or when pulled really fast it can become quite annoying (which is the whole purpose of it, actually).
