Physics trivia quiz asks what happens to an aluminum can near a charged balloon

Original: # Electromagnetism_trivia If you rub a plastic balloon with some wool or synthetic material, and put it close to an alum

An astrophysicist has posed an electromagnetism trivia question: if you rub a plastic balloon with wool or a synthetic material and bring it close to an aluminum can resting on a nearly frictionless table, what will the can do? The puzzle invites people to reason about static electricity and induced charge, and is drawing answers and debate from science-minded followers.

Why now: The static electricity puzzle is challenging enough to spark discussion among physics enthusiasts online.
