On November 19, TRECA Digital Academy students visited the American Whistle Corporation in Columbus, OH.
The American Whistle Corporation is the only manufacturer of metal whistles in the United States. This company manufactures whistles for a variety of customers including the NFL, police departments, and Amazon. Students learned that the whistles are made out of brass, using soldering paste to seal the gaps in the pressed pieces of metal. The American Whistle Corporation uses a combination of modern and traditional machinery, with some equipment still in use dating back to 1905.
Students also learned about the small ball in some whistles, called a pea whistle. The cork ball vibrates when air is blown into the whistle, causing slight changes in pitch and a more shrill sound. The pea whistle is very popular, and students saw the making of one from beginning to end. At the end of the tour, students received their own metal whistle and created their own customized plastic whistle themselves. Our students and families thoroughly enjoyed this unique tour learning about the history and manufacturing of whistles.
