Find the odd one out based on the vibrating material producing the sound:
Blowing air into a flute
Whistling with the mouth
Blowing across the open top of a bottle
Plucking a rubber band stretched between fingers
Solution
Flute, whistling, and blowing across a bottle all produce sound through vibrating air columns, whereas plucking a rubber band produces sound through a vibrating solid strip.
