This real-life Thor hammer can only be lifted by its creator

Marvel's Thor would be nothing without his Mjolnir - a square-headed lump hammer made of fictional super-metal"uru". The Mjolnir only answers to Thor and is inscribed with the words: "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor."

A YouTuber who goes by the name of Sufficiently Advanced is "worthy," if his latest video is anything to go by. He has made a replica Mjolnir that only responds to his touch - much to the surprise of the baffled onlookers in Venice Beach, California.

The "working" hammer has a fingerprint scanner in the handle that deactivates an electromagnet in the head of the weapon.

The electromagnet - taken from a microwave oven - is connected to four batteries and activates when the hammer's handle is grasped. Sufficiently Advanced cased this technology inside an authentic-looking Mjolnir design.

Are you worthy enough?

Sufficiently Advanced has dedicated his recently-launched channel "to making pretend things into real things." The hammer video follows a video explaining how to make a Rasengan -  a blue ball of light that forms in the hand from the Naruto anime comic.
