How did you make whistles? I have a bike trailer that houses the whistles and jigs and tools and the solar panel that charges the battery that provides the power to run the pyrography pen that draws names on the whistles.... I call them eco whistles with a nice shiny raw linseed oil finish. Perfect for kids to annoy adults!
The bicycle solar powered whistle factory is ready and available for demo's and events!
