One of the commenters had an interesting remark about the video:

I just had an awesome idea, instead of the fringerprint scanner make it remote controlled, so you can activate and deactivate the magnets (or however magnets work) remotely, then go to comic con and ask people to pick it up and only deactivate the magnets for people in Thor costumes. This will make some people crazy!

Uh well some people may find that funny and others potentially not.

We hope you like the video and we will keep you updated on more cool experiments.
