How to Make a Mobile
The video below gives one way of preparing a mobile, but the fun is to use your imagination in hanging the pieces so that they balance.

Science Magic
An object or group of objects, such as a mobile, always hangs so that its center of gravity (CG) is in line with or below the point of suspension (pivot point-where it is supported)
The diagram of the balancing hammer belowis a still shot from the video. As long as the center of gravity of the system (yardstick, string, hammer) is in line with the pivot point (where the system is supported) it will balance.
