Newton's inertia beads
This online resource shows the steps taken for a teacher demonstration that focuses on the concepts of inertia, energy and motion in general.
In this demonstration, a long string of beads is given a slight tug and practically pulls itself out of a container and onto the floor.
The web page includes an explanation of how it works and how to take the demonstration further.
This teacher demonstration could possibly be a student practical activity, if you have enough equipment for students to use in groups.
