The Science Guy is doing whatever it takes to educate us.

Ahead of the Season 2 premiere of "Bill Nye Saves the World," Netflix dropped an official trailer on Wednesday. The video previews the topics the show's host, Bill Nye, will explore in the upcoming episodes, and they range from curing tuberculosis to time travel. At one point, the scientist-slash-TV personality even buys marijuana, noting that he is doing it "for science."

Like the first batch of episodes, Season 2 will take on scientific issues that have the potential to affect us all. The upcoming episodes will do so with more of Nye's trademark enthusiasm, showy experiments, and high-profile guests that hail from the worlds of entertainment and science. Some of those names you'll likely only recognize if you're a scientist yourself, but there are other guests you'll probably be more familiar with, including model Karlie Kloss, actor Zach Braff, and comedians Drew Carey and Ali Wong, among others.

"Bill Nye Saves the World" Season 2 premieres Dec. 29 on Netflix.
