About the event
When fog or poor weather moves in and blocks out the light from the lighthouse, sailors relied on sound signals to help them determine their location on the water. Learn how the evolution of these sound signals happened from gunpowder, to steam, to compressed air, and now electricity.
The highlight of the presentation will be the DEMONSTRATION of each signal! HEAR a cannon's roar, a steam whistle's melodic tone, and the sharp honk of a diaphone horn. Don't know what a diaphone is? You will!
Local history buff Jake Heffernan of the Kewaunee Lighthouse will walk us through this journey, using a portable compressed air system which powers a 5" diameter steam whistle and a small "diaphone" horn. A small (3/4" bore) cannon is used to demonstrate the fog cannon.
Ticket proceeds benefit the restoration of the Kewaunee Pierhead Lighthouse.
