Bella is in a music box that helps her dance.
Bella the Ballerina is simple design, involving a dc motor to create centripetal force to spin the ballerina. The dc motor has a constant centripetal acceleration relitvley slow, in result, the ballerina will complete a full cycle about every 2 seconds. The lights at the side of the box, and the buzzer are for added effect. The end result of the ballerina is for entertainment with music and a dancer to follow the music.
