In this very exciting episode of The Show About Science, Nate talks to Santa Claus about the science behind his workshop and what happens when kids send drawings of new toys for Santa to produce in his present factory. Santa than suggests that Nate talk to Roger, his Head of Research and Development. Roger gives Nate an inside glimpse into the science behind reindeer flight and the tech that allows Santa to deliver his presents in one night. Roger is also the author of The Physics of Christmas: From the Aerodynamics of Reindeer to the Thermodynamics of Turkey (http://amzn.to/1NwaZr4) and Can Reindeer Fly?: The Science of Christmas (http://amzn.to/1NwaYDG). Finally, Nate talks to Lt(N) Marco Chouinard from NORAD about the science of tracking Santa and the noradsanta.org website. Kids can also call NORAD on December 24th to find out when Santa will be arriving in their area. The number to call is 1-877-446-6723.
