So is very likely that your Christmas tree is not a pine. ___________________________________________ Credits (and Twitter handles): Script Writer: Henry Reich (@MinutePhysics) Script Editor: Alex Reich (@alexhreich) Video Illustrator: Ever Salazar (twitter:@eversalazar) Video Director: Henry Reich Narrator: Henry Reich With Contributions From: Emily Elert (@eelert), Kate Yoshida (@KateYoshida) and Peter Reich Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder _________________________________________ Like our videos?
