A 90mm diameter plastic ball with a PP3 battery powered tone generator and
speaker contained within. The ball can be safely whirled round in a large
horizontal arc to demonstrate the doppler effect. Good output volume and
variable tone pitch provide all that is required for a dramatic study of the
doppler shift associated with a moving source.
