Waterparks are the result of humanity's hubris of science.

In this one, Ian and Liv revisit one of their favorite episodes for Disaster Hour's 3rd Birthday: Action Park! Throughout the 1980s, Action Park was an outdoor waterpark with waterslides that were straight out of a Stephen King novel. They were dangerous, exhilarating, and built with zero professional architects or rollercoaster engineers. Guests were injured, the park faced lawsuits, and the owner continued dodging the law for decades. Welcome to Action Park!

Also, Justinepremieres as a new guest. Liv doesn't know how to use a calculator. Libby has imaginary friends. Dylan continues winning at life. Bob jumped off a cliff once. Ian confuses Tony Hawk and Stephen Hawking.

There's a right and wrong way to riot, everyone.

In this one, Ian and Liv talk about a riot that broke out in Vancouver after the 2011 Stanley Cup finals. And it's confirmed to be a fact, that the best way to mentally process your team's loss, is destroying the city in which they're based. Hashtag sarcasm.

Also, Liv's high school math teacher is dead. Ian fantasizes about being placed under house arrest.

Dangerously close to danger.

In this one, Ian & Liv talk about a cruise from 2019 that got turned upside down (almost literally) when the ship lost power mid-cruise in rough seas. The rescue efforts were daunting, passengers were injured, the grand piano was damaged, but the snow grotto was unharmed.

Also, Liv faces her fear of cruises. Ian loses all creativity.

Coconuts have a shockingly high street value.

In this one, Ian and Liv talk about an island off the coast of India where the inhabitants have remain completely uncontacted by the rest of the world, and have defended their island with primitive violence for the last 200 years. Despite local laws prohibiting island interaction, people (yes, plural) have tempted their fate on North Sentinel Island.

Also, Ian comes up with a new podcast idea. Liv redefines dating.

Season 10 is here!

In this one, Ian and Liv talk about a cosmic anomaly where the Sun launched a solar storm of magnetism and plasma that blasted the Earth in 1859. The result? Wild auroras and electrical malfunction across the planet. Was it the end of times, or just regular times? Spoiler: it was both and neither.

Also, Liv wishes the Earth would lose power. Ian quotes Charlie the Unicorn.

Remember what Uncle Stockton taught us: safety is just pure waste.

Get ready to look back at THREE YEARS of Disaster Hour! This episode has games, nostalgia, more Bob content, and an endless supply of clips from the last 99 episodes from Ian and Liv!

Don't forget to thank a horse!

Season 9 was atypical for Ian and Liv in so many ways, so here's the content that didn't make the final cut for all of the season 9 episodes! Enjoy almost a half hour of nonsense, camaraderie, verbal hostility, and straight up miscommunication on the set of Disaster Hour!

Bacon can kill you in vast number of ways.

In this one, Ian and Liv revisit the first episode of Disaster Hour: THE one and only Lucy Walker Steamboat, and, of course, her devastating explosion on the Ohio River. Steam engine technology was unregulated, the engineers had no formal training, and alcohol was in the air. Surely, nothing can wrong, right? Well, it can, and don't call me "Shirley."

Also, Ian holds a grudge against a former coworker. Liv reminisces on growing up with an Italian mother.
