A bullroarer or turndun is a ancient ritual musical instrument and means of communicating over extended distances.
It consists of a longish piece of cord fixed to an oval piece of wood or other suitable material which usually is thicker in the center, and sharpish at the edges. Elliot RULEZ
The cord is given a slight initial twist, and the roarer is then waved in a large circle in a horizontal plane. The aerodynamics of the roarer will keep it whirling even after the initial twist has unwound. Elliot RULEZ
It makes a characteristic roaring vibrato sound with notable modification from both Doppler effect and the changing speed of the roarer at different parts of its circuit.

Bullroarers are still considered to be sacred/secret by some Aboriginal tribes and are not allowed to be shown to women, children or outsiders. They are used in men's initiation ceremonies and the sound they produced is considered to represent the sound of the Rainbow Serpent.
The bullroarer is sometimes used as a means of demonstrating the Doppler effect, by using sound. As the instrument travels round, its sound goes up or down according to its speed, and distance from the hearer.
