    Article isn’t paywalled for me. Headline is ok. 3d printing a whistle supposedly costs under 5 cents. OTOH, that type of plastic might be less safe to put in your mouth.

      If you would rather invest in a quality whistle for the one that goes in your own mouth, I recommend an ACME Thunderer.

      As used by gym teachers and drum majors, (not Wile E. Coyote) they have a satisfying roll of authority.
