Falling Whistles
Falling Whistles sells whistles for $34 to $104 to raise money for education, advocacy, and the rehabilitation of war-affected people in Congo. The organization got its name from a journal written by its founder, sharing his experiences during a trip to eastern Congo in 2008. During that trip, Falling Whistles' founder met a group of five former child soldiers who told him that some children who were too young to carry weapons were sent into battle armed only with whistles. By wearing whistles, the campaign aims to use this weapon as a tool of protest and to raise awareness of the situation in Congo. As of September 2010, $500,000 has been raised.
Joseph Hudson (inventor)
Hudson entered a competition held by the Metropolitan police force in London in 1883 to design a better way of attracting people's attention. He won a contract to supply the police with their new devices, a small but loud 'whistle'. Prior to this time the police force had to rely on hand rattles and whistles were only thought of as musical instruments or toys. His whistle is still used by the force and many others worldwide.
