One man combined an electromagnet from a microwave with a fingerprint scanner to create a Thor hammer that only he can lift. Cue every would-be kid scientist-slash-comic-fan begging, "Can we do this?!"
"In Marvel comics, Thor's legendary hammer Mjolnir is famous for being able to be wielded only by the worthy. For the unworthy, i.e., literally everyone except Thor and the odd someone else from time to time (a handy loophole for writers), Mjolnir simply cannot be lifted off the ground.
It is this property that electrical engineer Allen Pan, aka Sufficiently Advanced on YouTube, decided to replicate in his very own take on a 'working' Mjolnir."
