"Participants received a standardised acrylic plastic didgeridoo that was developed by the instructor in collaboration with Creacryl GmbH (Ebmatingen, Zurich, Switzerland, and costs €80 (£43; $94), fig 1). The didgeridoo is 130 cm long with a diameter of 4 cm and an elliptical embouchure with a diameter of 2.8-3.2 mm. Acrylic didgeridoos are easier for beginners to learn on than conventional wooden didgeridoos."

Two wrongs can make a right.
Oh, did you make use of the central telephone service did you? You didn't send the list by carrier pigeons?
You'll hear Charlie McMahon going at it with continuous circular breathing for five to eight minutes or so on the early Gondwanaland albums (along with sliding length didgeridoo effects and 'singing' down tube).
