Helta3 is the man when it comes to making veggies into instruments, as a recent YouTube search of "vegetable instruments" proved. Some of these videos are below, including the very first of the five, which is a general introduction to handmade veggie musical instruments by Helta3. In it he demonstrates playing such veggies as asparagus, cucumber, paprika, broccoli, and carrots -- which he plays as both an ocarina and as a panpipe.
Check out Helta3's YouTube page to see him make and/or play other veggie instruments such as a radish and a cabbage, also as an ocarina (who would have thunk?). By the way, the exact definition of an ocarina, as per the Webster dictionary, is "a simple wind instrument typically having an oval body with finger holes and a projecting mouthpiece." The other veggie musical instruments videos below include a vegetable orchestra, two funny guys playing veggies, musical foods, and a how-to guide to make your own carrot ocarina.
