WHISTLE YOUR WHISTLE

 Whistles have been around the United States and Europe since 1884. However , whistles were used bach in Greek and Roman times to carefully keep prisoners in order. Whistles were made of soft hollowed wood or bone and the whistler could make the whistle hum high and low pitches. Basically a whistle is an object that makes pitches when air is forced into it.

These days whistles are used by coaches, police, referees, tea kettles when the water has boiled and campers. Campers use whistles to gather everyone for dinner. A whistle may be needed in a rescue. A whistle can ce used as a form of communication for campers.

Since the early time when whistles were made of bone or wood it took until 1886 to make a steel whistle for a referee. This was done in England. Today we have a choice between metal and plastic. Metal is heavier and it sinks, it also rusts. Plastic whistles float, do not rust , are lighter, and are about  1/3 the cost of metal whistles. Comes with a  lanyard.
