Making a Coin Spin with Forks and Batteries

The video tutorial demonstrates an experiment involving batteries and forks to create the illusion of a coin spinning. It begins by listing the materials needed, including four forks, four batteries, and a coin. The setup involves arranging the forks in a square and placing batteries at the corners. A variation with fewer materials is also mentioned. The tutorial explains that the setup is a trick to conduct electricity, but the coin won't spin naturally. Instructions are provided for recording the experiment and editing the video to create the illusion of a spinning coin.

Explain the principle behind the experiment.

What should you do after spinning the coin?
