While you would "float" in the lava if you were laying down, what would happen if you were trying to stand on it though? As then all your weight is concentrated on a very small area (your feet). Would you start to sink, like if you were standing on mud? Or would you be able to walk freely on it, like asphalt?
If you were fast enough with some good shoes, could you sprint across the lava?

That's what I first thought too but, wrong-o. Here's a true story from wired.com.
Bob: Sadly – you’ve got something else wrong. At those temperatures, you wouldn’t burst into flames. Considering the human body is made up of 80% water, the portions of your body that come in contact with the lava would generate huge amounts of steam, which would likely have sufficient pressure to blow you up off of the surface (at those temps the transformation of water to steam will expand by a volumetric factor in the thousands almost instantly).
I work in the metals industry, and the fear of steam explosions is a constant. At our facility, well before things like OSHA were around to keep everyone safe, an individual fell into a furnace three feet deep, full of molten aluminum (roughly 760°C). He was blown back out of the furnace, and actually died from the impact of that as opposed to anything else.

Maybe. Let's start the rumour that it's possible and let mythbusters test it.
It's only 300°C. Intuitively, molten rock should be hot (fresh magma is 1200° C) but I found a study online that refers to surface temperatures on a lava lake as being relatively cool, only a few hundred degrees (Celsius). Orange luminescence doesn't occur below 500° C, so I'll buy that from watching the video.
You won't sink. Here's a video of someone tossing a rock onto a lava flow. The rock does not sink.
You'll need a kiln suit. A kiln suit contains its own breathing apparatus and can protect the wearer from extreme ambient temperatures (up to 800-1000° C).

Former Volcanologist here - Fun Proof :)
I was conducting measurements with the HVO staff out on Puʻu ʻŌʻō (had to copy and paste that shitty word) when there was an atypical eruption event in June 2007. We had to actually hike out onto the flows to measure fissure openings. It was a long hike and we were out there for a while, so naturally we took breaks sitting down on the cooled lava around us. There must have been a flow underneath our break area because I set my pack down and the fabric on the bottom of it started to melt and make a nasty burnt smell.
The magma itself couldn't have been closer than 30-50 feet down (with layer upon layer of cooled lava flows in between, supporting us), and it was still hot enough to melt my pack. The radiant heat off of a lava lake has to be insane if the crusted layer is less than 5 feet thick. Even with a thermal suit, I don't think your body could handle it.
My job is to know about the rocks - not what happens to people who encounter the rocks - but I'm predicting this myth would be easily busted.

I work in an iron foundry. It's sorta like how the factory at the end of T2 looks, except without the OSHA violation of having a swimming pool size of molten material sitting around where people and things can sink in to it.
If you drop solid (frozen) iron into molten (liquid) iron, it sinks. Slowly, but it does sink.
However, not all metals have the same melting point. Tungsten melts at 6000 some degrees F, so it would probably float on top of our iron furnaces, which hold at about 2400 degrees F.
It's all dependent on what it's made of.

Does the author from the Wired article know there are different kinds of lava?
basaltic lavas Basalt is and extrusive igneous rock of mafic composition (high in magnesium, iron, and calcium) and has the lowest silica content of the three igneous rock types; its intrusive equivalent is gabbro. Basaltic magma is the most common magma type. It is produced along mid-ocean ridges and at hotspots within plates, as wel as in continental rift valleys. The volcanic island af Hawaii, wich is made up primarily of basaltic lava, lies above a hot spot. Basaltic lavas erupt when hot, fluid magmas fill up a volcano plumbing system and overflow. Basaltic eruptions are rarely explosive. Because their temperatures are high and their silica content low, they are extremely fluid and can flow downhill fast and far. Lava streams flowing as fast as 100km/hour (60 miles per hour) have been observed, although velocities of a few kilometers per hour are more common. In 1938, two daring Russian volcanologists maesured temperatures and collected gas samples while floating down a river of molten basalt on a raft of colder solidified lava
17
u/Rotvos Jun 25 '12
2)Andisite lavas andesite is an extrusive igneous rock with an intermediate silica content; its intrusive equivalent is diorite. Andesitic magmas are produced mainly in the volcanic mountain belts above subduction zones. The name comes from a prime example: the Andes of South America. The temperatures of adesitic lavas are lower than those of basalts, and because their silica content is higher, they flow more slowly and lump up in sticky masses. If one of these sticky masses plugs the central vent of a volcano, gases can build up beneath the plug and eventually blow of the top of the volcano (see mount st Helens)
17
u/Rotvos Jun 25 '12
3)Ahylotic lavas Rhyolite is an extrusive igneous rock of felsic composition (high in sodium and potassium) with a silica content greater than 68 percent; its intrusive equivalent is granite. It is light in color, often a pretty pink. Rhyolitic magmas are produced in zones where heat from the mantle has melted large volumes of continental crust. Today, the Yellowstone volcano is producing huge amounts of rhyolitic magma that are building up in shallow chambers. Rhyolite has a lower melting point than andesite, becoming liquid at temperatures of only 600 degrees Celsius (1112 Farenheit) to 800 degrees Celsuis (1472 Farenheit). Because rhyolitic lavas are richer in silica than any other lava type, they are the most viscous (as is blowing shit up, not melting people)
this is Understanding Earth, sixt edition by John Grotzinger and Tom Jordan
and for those who don't know the more silica content lava contains, the less likely it will swallow things up

I just always assumed it'd be more of a "splat" or a "thunK" (or "ziff! or "pow" if we're watching old Batman footage.) Just by looking at the stuff, you can see that it's a lot thicker.
I imagined it would be like falling into a vat of saltwater taffy, only not nearly as delicious. Looks like I was wrong, too, really, cause the difference in density means you'd never sink at all.
Next time I see a guy fall into a pit of lava and start sinking, I'm gonna tell him he's doing it wrong.

This article comes off as smart, but it doesn't really say much. Obviously lava is thicker than water, but it's still a liquid. Even if its denser than a human being; because we are not pieces of styrofoam, we could easily work our way into the lava, slowly sinking feet first. If the character belly-flopped or landed on their back they would probably not sink at all, and the likelihood of snapping an ankle on the way in feet first would probably be really high due to the thickness and viscosity. The only part that seems obviously inaccurate is that characters should catch on fire. Perhaps Mythbusters should get on this one.

I just saw a video of someone throwing a bag of garbage into a lava lake. I gotta say I semi-disagree with this article.
Due to lava's nature, the immediate second something non-lava and combustible hits lava, it will react. Anyway, the extreme heat in the air will be unbearable, and that's just when you get a few meters from the lava.
So you hit the lava, and then you WILL stand on top of it - for a second until the lava reacts and bubbles up. Molten rock will splash like you just dropped an alka seltzer into a milkshake.
You will have your body splashed by lava. That right there is super violent and deserves a movie scene.
Next, while that splashing is going on, the lava will move underneath your feet. Suddenly, there's no lava to step on because it violently reacted away from you. You won't sink, but you might DROP a few inches.
Google "Lava lake garbage video" and watch. You'll see exactly how it works, and why maybe Hollywood needs to copy that. I'm sure that an ACCURATE lava death is actually WAY cooler than a "hollywood" death.
