Unbreakable Thread Force And Motion Science Experiment
In this fun and easy force and motion science experiment for kids, we’re going to investigate unbreakable thread.
- Wooden cloths hanger
- Thin wooden stick
- Two pieces of thread
- Metal edged ruler
- Tie one piece of thread to each end of the wooden cloths hanger.
- Now tie the free end of each thread to each end of the wooden cloths hanger so that the wooden stick is suspended below. Do so in a way that the wooden stick hangs about twelve inches below the hanger.
- Now hit the stick with the metal edge of the ruler.
- The stick will break before the threads.
How it Works:
Because of inertia, the stick will attempt to remain at rest so much it would rather break than move.
Make This A Science Project:
Try pencils or wooden dowels that are larger in diameter. Try thicker pieces of string or yarn.
