How is Santa able to tell who's naughty and who's nice? How can he travel around the entire world in one night? Laci explains what kind of high tech arsenal Santa has to make it all happen.
It's the science of Santa in this episode of DNews, as Laci puts the rumors to rest. Santa Claus is real and she'll break down how his Christmas miracles are actually grounded in science. Everything from he compiles his massive "naughty and nice" list to how aerodynamic his sleigh is; it's all broken down. Prepare to believe!
