Zusammenfassung:The paper describes the mechanics of cherry pit projectiles and ends with showing the similarity between cherry pit launching and chameleon tongue projecting mechanisms. The whole story is written as an investigation, following steps that resemble those typically taken by scientists and can therefore serve as an illustration of scientific reasoning and how scientific knowledge is built. (Contains 5 figures, 2 boxes, and 1 footnote.)
