What do swamps have to do with Will O’ The Wisps — and why are they some of the most important ecosystems on Earth?

In Part 2 of our Will O’ The Wisp series, Lauren and PJ shift from folklore to the fascinating science of swamps. We explore how swamps form, what makes them unique ecosystems, and why anaerobic decay plays a critical role in producing the gases historically linked to mysterious glowing lights.

Along the way, we break down wetland ecology, decomposition without oxygen, methane production, and why these often-overlooked environments are vital for biodiversity, flood control, and climate regulation.

Plus, PJ debuts an original parody song, “Anaerobic Decay,” a science-themed twist inspired by “Party in the CIA” by Weird Al (which itself parodies “Party in the USA." Its like, Inception or something). It’s educational. It’s ecological. It’s unexpectedly catchy.

If you’ve ever wondered what’s really happening beneath the surface of a swamp — this episode gets into the mud.
