Another fun activity from Scientific American.
Have you ever seen a mobile? Not a mobile phone—but a hanging art sculpture? You might have had such a mobile in your room when you were little. These mobiles hang in the air and are usually made up of layers of hanging balanced rods, which, in turn, have objects hanging from them. When you look at a mobile sculpture you might wonder how it stays balanced—even when it is in motion. In this activity you will make your own mobile sculpture and find out.
