Lava: primal force, essence of destruction that leaves behind fertile land; ''really, '''really''' hot''.
Line 406 ⟶ 407:
* Mounty Oum's CG [[Fan Film]] series ''[[Dead Fantasy]]'' probably takes this to its most extreme. During part II, the fighters end up on a stone raft floating down a river of lava. The raft is less than a foot thick, but does not melt or overheat. Similarly the girls suffer no problems from heat and toxic gas. Sounds pretty standard so far. Then Tifa gets knocked off of the raft. Yuna shoots Tifa to knock her onto the rocky ledge rather than into the lava, implies that falling in the lava would be a bad thing. But Tifa then proceeds to RUN ACROSS the lava, suffering no more than ignited shoes, used to deliver a fiery dropkick.
** Used again with Tifa and Hitomi's [[Battle Amongst the Flames]]. The whole church is on fire? No problem, it just makes an awesome backdrop to the fight.
* [https://web.archive.org/web/20160602191223/http://kvts.smackjeeves.com/comics/365423/its-solid/ A particularly blatant example.]
* [http://wayofthemetagamer.thecomicseries.com/comics/pl/34423 Lampshaded in] ''[[The Way of the Metagamer]]''.
* [[Averted Trope|Averted]] and [[Lampshade Hanging|lampshaded]] in the [[Whateley Universe]]. Team Kimba is in a holographic simulation of an evil lair inside a volcanic mountain, complete with a huge gap across molten lava to get to the [[Big Bad]]. [[The Smart Guy]] points out that even the toughest supers on the team wouldn't survive flying above the magma, and snarks that it isn't some stupid video game. But they have other resources.
Line 487 ⟶ 488:
* ''[[American Dad]]'' episode "Magnificent Steven", they find lava deep beneath a certain Washington landmark and play it straight by featuring a bridge a couple feet above it while mocking it all the while:
{{quote|'''Steve:''' ''I can't believe there's lava under Washington, D.C.!''
'''Stan:''' ''{{spoiler|Where do you think all the [[PunA Worldwide Punomenon|hot air]] comes from?}}'' }}
* ''[[Ben 10: Omniverse]]'' episode "Hot Stretch". Aliens use a stolen fusion device to unleash lava on the surface. The lava flows in rivers down city streets without setting anything on fire and people stand next to it with no harm (although the heroes do sweat a lot, which is more than seen in many shows).
* In ''[[The Owl House]]'', the Boiling Isles are so named because they are islands in a boiling ocean - if real-world physics were to be applied, this would cover the Isles with superheated steam, making it not even remotely inhabitable

* Kids are familiar with this trope from a very early age. They will often pretend that the floor is "hot lava," the point of the game being to move around the room without touching the floor. This game is familiar enough to have been referenced on an early ''[[Grounded for Life]]'' and a vacation episode of ''[[The Simpsons (animation)|The Simpsons]]'' as well as the nudist episode of ''[[Family Guy]]'', an episode of ''[[RWBY Chibi]]'', and a mission in a Tony Hawk game.
** [http://xkcd.com/735/ This] ''[[Xkcd]]'' comic sums it up well.
** There is even [https://en.wikipedia.org/wiki/Floor_Is_Lava a game show] on [[Netflix]] based on it.
* Subverted a bit by [http://youtube.com/watch?v=4b6n8riJaFo the Discovery Channel].
* In older aluminum plants, the metal is still poured partly by employees who work very close to 1300-1700 °F aluminum - often as close as a foot or less distance between the worker and the aluminum. Dross is skimmed from the tops of crucibles and molds with hand-held metal skimmers. The workers wear heavy cotton gloves, double cotton sleeves and aluminized aprons to do this. While it is not the most comfortable job in the world, the protective gear does not singe or burn unless in direct contact with the metal, and the cotton is not fire retardant.
** Further, the most important bit of safety gear: a sort of awning over the tops of your boots. Molten Aluminum can run down denim, barely scorching it (ironically, its convection acts on the water vapor to act as a temporary "force- field"), but bad things happen if it gets in your boots and it can't flow anywhere else.
*** Kind of brings a whole new layer of meaning to "flares", that does:)
* Played pretty darn straight by the experience of Heimaey, Iceland, in the Vestmannaeyjar islands. In 1973, a nearby mountain erupted, sending, literally, acres of lava towards the town - and, from the inhabitants' perspective, more importantly, the harbor. In a desperate attempt to save the harbor from being filled by lava, the inhabitants, the government of Iceland, and, eventually, even the U.S. Navy, started pouring water directly on the lava to try and solidify the leading edge, hopefully sending the remaining lava ''somewhere else''. This took weeks, if not months, and for most of that time, not only were people walking directly on top of the lava, they were separated from actual liquid rock by, at times, ''nothing but ash'', but they were running hoses along it, and even driving ''bulldozers'' around on top of it. The treads of the bulldozers blued from the heat over time, and the soles of boots tended to melt when people stood, but for a significant amount of time, people were not only running near lava, they were working on top of it for twenty-hour-a-day stretches. Icelanders are hardcore.
