See how you can demonstrate First newton's Law and Inertia using a simple Bead Chain Experiment.
This demonstration is an excellent learning tool for Physics and demonstration of Inertia - the object's tendency to continue doing what it was doing - if it was moving to continue to move and if it was resting to continue resting.
All you need is a big enough Cup and a Bead Chain - mostly used for decorating Holiday tree.
Explanation of the Inertia Experiment - Why does it jump upwards?
What is this sorcery? How are beads defying gravity?
The phenomenon of “chain fountain” caught the public's attention when it was showcased in a RU-vid video by Stephen Mould in 2013. It caused lots of attention and research in the physics community. The key is in the structure of the chain and the fact that beads are connected to each other. When pulled upward, links connecting the beads rotate, and beads bump into each other. This produces a huge downward force on the opposite end of the chain. That, as we know from Third Newton’s law means that the opposite force of equal magnitude is created. So our seemingly small pull generates huge push from the other side of the chain which causes beads to go upward.
