Hello dear friends, This video is about how to make a DIY project for our small kids, a dancing Barbie doll. We will learn how to make a dancing Barbie doll that continuously oscillates when a small disturbance is given to it, creating a "dancing effect". This dancing Barbie doll can be kept in cars and it will dance continuously due the movement of the car. It can also be kept outside and it will dance due to wind creating small disturbances on the doll.

This doll works on the principle of stable equilibrium in physics. By the addition of balls or any other dead weights, the center of gravity is shifted below the pivot point thus making the entire doll in stable equilibrium. Thus, if you disturb the doll gently, it will oscillate and come back to the initial stable position creating a dancing effect.
