Wow. This is kinda like the gadget that Pyro (the comic book version, not the movie one) uses. Suddenly the idea of a teenage kid inventing web-shooters to fight crime and swing from building to building doesn't seem so implausible anymore.
At least that one works. This movie, which purports to show you how to create hover shoes, is not as credible. I don't think The Wizard has anything to worry about.
