Bill Nye is, famously, the Science Guy, so he’s an expert on pretty much everything. Including, it would seem, the strange physics and parallel universes that make the Upside Down possible in Stranger Things.

Netflix combined Stranger Things and Nye’s new show, Bill Nye Saves the World in a short promotional video on Wednesday, and dang if they don’t go together better than syrup and Eggo waffles. In the video, a bow tie-clad Nye listens to Mr. Clarke, the affable geeky science teacher on Stranger Things, teach the boys about parallel universes. Nye then steps in to explain multiverse theory a little more in depth. It’s all pretty complicated stuff, and conveying the information requires parallel-universe Nyes.

Ultimately, Nye concludes that the telekinetic powerhouse Eleven is probably behind everything. Sounds legit.

This isn’t the first time that Netflix has mashed up one of its new shows with Stranger Things. Earlier this month, they shared a similar promo where Jonah and the bots from Mystery Science Theater 3000 riffed on the opening moments of the Stranger Things series premiere.

Bill Nye Saves the World is currently streaming on Netflix. The second season of Stranger Things will premiere on October 31, 2017, aka Halloween.
