Mark Rober shares his trick to win a coin toss

Former NASA Engineer turned YouTuber Mark Rober is probably best known for his anti-porch-pirate Glitter Bombs but, during a longer First We Feast segment, he shares his trick for always winning a coin toss.

Mark has a new project in the works, a "hidden-camera, science-focused prank" show on Discovery Channel called Revengineers.
