Watch as People try to Lift this Advanced Thors Hammer with Comic results
This is the sort of thing that makes Science interesting and as I studied Electronics when I was younger it makes me wish I would have kept the technical side going. Check out the way this hammer just sticks to the floor (metal) and how only the designer of the hammer can actually lift it. Design a powerful electromagnet and a disabling fingerprint scanner and you have some comedy moments well worth watching. A cheeky video and a great design/integration of simple technology.
