Kurt Hugo Schneider https://www.youtube.com/watch?v=z0JpgEOLezY Creator: Dianna Cowern Editor: Jabril Ashe Animator: Kyle Norby Thanks to: Anne Wojcicki, the 23andMe staff and Dan Walsh I first heard this riddle from Derek Muller of Veritasium during a talk he gave. It stuck with me as a fun hands-on riddle to ask in person. Plus he gave me his blessing to use it in a video. He hates riddles anyways. ••••••••••••••••••••••••••••••••••••••••­­­••••••••••• Keep up with my less sciencey shenanigans: INSTAGRAM: http://instagram.com/thephysicsgirl TWITTER: http://twitter.com/thephysicsgirl FACEBOOK: http://facebook.com/thephysicsgirl
