Didgideroo mouthpiece for BoomWhacker tubes

This is a mouthpiece designed to turn classroom BoomWhackers into a functional (though primitive) didgeridoo for demonstration. It will decrease the pitch slightly due to the increased length, but seems to work well.
Can also be used as a buzz trainer for students (especially SpEd) who have a hard time grasping the concept of sealing on a mouthpiece and buzzing the center of their lips. The deep loud pitch of the boomwhacker assembly will provide immediate feedback
