Buzz Like a Bee

Make a spinning device that creates a buzz-worthy vibration 
Observations and results
Moving air flowing over the rubber band makes it vibrate the same way wind blowing over a flag makes it wave. These vibrations produce sound, like the strings on a guitar do. As the rubber band vibrates, it shakes the entire contraption including the index card. Because the vibrating index card moves along with the rubber band but pushes a lot more air than the latter it amplifies the sound. Did you find ways to change the pitch of your contraption's sound?
