he science of static electricity and friction makes this matchstick rotate.
When you cautiously balance a matchstick on the rim of a coin that has also been precariously balanced onto another coin, it might sound like rotating the matchstick will cause it all to come tumbling down. That might be the case if you were to use your hands. What if you were to use static electricity to rotate the matchstick? Would that even work? We’ll show how this isn’t just possible, it’s downright cool.
