(Lost the photos of the sound components)

1. I attached three tiny bells ties together with fabric string onto the model. The fabric allowed for a more flexible movements so that the sound is less constant and more musical.
2. Connected a resistor to the circuit because the original speed of the motor was really fast and produced a sound similar to an alarm which was more scary and slightly irritating as oppose to joyful.
3. The bells knock against four surfaces when spinning. I covered two out of the fours surfaces with copper so that the bells hit different surfaces as it spins, producing more variation in sound.
