Guy creates a real-life version of Thor's Hammer

An engineer has created a real-life version of Mjölnir, Thor's mythical hammer that can only be lifted by someone as powerful as himself. The feat is achieved by using a strong electromagnet that gets deactivated via a fingerprint scanner! The only catch is that the trick only works on surfaces made of a magnetic material (or until the batteries are empty).

A replica of Mjolnir (Thor's Hammer) from The Avengers that's pretty much unliftable unless you've got my fingerprints!
