A do-it-yourself hacker has created something straight out of comic book fantasy: a hand-mounted laser that burns hot and bright enough to blind a human or set flesh on fire.

Making use of a 1,000-mw, 445 nm laser, hacker Patrick Priebe appears to have designed a real-world version of Iron Man’s hand cannon. In a video demonstration published to YouTube, he used it to pop balloons, cause fabric to smoke and cut through dense fog.

We can’t help but wonder if something like this could ever get through an airport security checkpoint.
