A world globe sculpture that turns on its axis would be a form of kinetic art.
Making rolling ball sculptures is a form of kinetic art. Kinetic art is art that has moving parts, such as a mobile that moves when there is wind or Newton's cradle, which moves with one ball hitting another. A rolling ball sculpture uses the force of gravity to roll the ball down paths, curves and zigzags. The material is open to the imagination but must be firm enough to hold the ball. Artists have created rolling ball sculptures from material such as wood, wire, paper and bamboo. (See Resources for the paper and bamboo and references for wood and wire examples.)
Instructions
1. Decide on the type of material for the sculpture such as wood, paper or wire along with how large you want to make the sculpture.
2. Find a ball or balls for the sculpture. The size of the ball will determine the size of the track. The track may be larger than the ball but cannot be smaller than the ball.
3. Make the tracks by forming curves, slopes and zigzags. For the ball to roll there needs to be a constant slope. Create an interesting sculpture by making multiple tracks that include curves and zigzags to make the ball roll from one direction to another.
4. Build a support for the tracks such as wooden legs or wire support rings. Attach the support using glue or nails.
