Fifty seven thousand Marvel movies later, you know the deal: Thor has a hammer (called the Mjolnir). Only he can pick it up. To pretty much anyone else, even those who are theoretically stronger than him, it’s impossibly heavy.
Bringing the concept to life, someone has built a Mjolnir… that only its owner can lift. How? Magnets!
