A science YouTuber has won a five-figure bet from a physics professor after he proved a wind-powered car could move faster than the wind while driving downwind.

Derek Muller, who runs the YouTube channel Veritasium, made the bet with Alexander Kusenko, a physics professor at the University of California, after Kusenko messaged him saying that it was impossible for the car to travel faster than the wind propelling it, according to Vice.

So Muller proposed a $10,000 wager with the professor saying that he could prove it. The pair signed an agreement to the bet, which was witnessed by Bill Nye and Neil deGrasse Tyson.
