Our favorite NASA dude is back with a brand new invention. Watch Jet Propulsion Lab engineer Mark Rober, the man with the most modern Halloween costume ever, turn an old-school Nintendo into a countdown clock that lets co-workers know it’s time to get the hell out of your office.
Want more Rober genius? He built an enormous Glowing Super Mario Kite. He cured our office boredom. He took us inside the Curiosity rover landing on Mars. He showed us how to blow a gaping hole in our chests for Halloween. He even showed us how to make our very own surveillance cam, Scooby Doo style. And his ugly Christmas sweater is better than yours.
