In this one, Ian and Liv talk about an oil rig that drills into a salt mine beneath a lake, which then causes the lake to drain into the salt mine, dissolving the mine, which creates a giant vortex of water that massacres the surrounding land and sucks in everything in it's immediate vicinity. So that's a lot to unpack.
Also, Liv struggles with basic concepts of maritime travel. Ian battles a stink bug in the studio.
