Twirl it over your head! Twirl it at different speeds and hear different pitches. The faster you twirl, the higher the pitch! A great way to discover the physics of music. Focus on signing in tune by singing into one end and listening in the other end. Measures 38" in length; this tube produces an 'F' pitch.
