In Vienna, Austria, there is a real musical ensemble called The Vegetable Orchestra, and every instrument is made from fresh vegetables.

Before each performance, the musicians carve carrots into flutes, shape leeks into string instruments, and hollow out pumpkins for percussion. No two concerts sound exactly the same because the vegetables change as they dry under the stage lights.

Founded in 1998, the group has performed hundreds of concerts around the world using instruments made entirely from produce, including carrot recorders, leek violins, cucumber “phones,” and pumpkin drums. After many performances, the leftover vegetables are cooked into soup and served to the audience.

It sounds like a joke, but it is entirely real, and it has even earned a Guinness World Record for the most concerts by a vegetable orchestra.
