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.
J Hudson &amp; Co
In 1883 Hudson began tinkering in his toolshed to make gadgets to sell, including whistles. After observing local police struggling to communicate with rattles, he realised that his whistle could be used as a tool. As the story goes, Hudson, a violin player, accidentally dropped his violin and it shattered on the floor. Observing how the discordant sound of the breaking strings travelled, Hudson had the idea to put a pea in the whistle. This gave it an ear splitting rattle that could grab attention even a mile away. After a demonstration at Scotland Yard, Hudson had his first sale.
