smh they go through all that trouble to make insane single-crystal nickel alloys to make jet turbine blades when they could literally just use a durian. We really hate taking the easy route

    Think of the smell, you haven't thought of the smell

    Mechanics would be passing out due to how bad the hanger bay smells.

    No it does not. Just because some YouTuber/tiktoker (I assume) said it, doesn't mean it's true.

    Probably tested it for a very short duration and also didn't measure surface-heat at that time. Even we humans can withstand 3000°C for a short time. Sure, it'll get loud, nasty and painful, but we wouldn't instantly perish.

    Steel can withstand much longer. And is probably more willing than a human.

    If we want to be entirely pedantic, everything can withstand any destructive condition for at least one plank time.

    I'd argue that your hand would probably even withstand a bit longer. Surely depends on what we set as "withstand"-boundaries :-)

    But that title suggested that durians could WITHSTAND 3k°C (which means surely a more prolonged time, like steel) not just not melt into oblivion for some seconds.

    I think I saw the video of it, they did it by holding a blow torch to it.

    But many videos like that are misleading because the person filming it doesn't know how blow torches work. They always hold the torch RIGHT up against the thing they're trying to burn, but you barely get any heat when you use it like that. You have to hold it a few inches back, right at the tip of the inner jet. That's where the hottest point is.

    Steel can withstand much longer.

    Undoubtedly.

    And is probably more willing than a human.

    ..willing? You think metal alloys have agency and capacity for consent? 😄

    Durians originally evolved to grow on sunpots. It's a testament of evolution that they've been able to adapt to the comparatively freezing temperatures here on Earth.

    "Why does this city smell so bad"

    It's not that bad..."

    "The supermarket smells like sewage and wet trash"

    Oh you mean that!? That's Durian

    You'll get a similar result with pineapple

    Dry durian fruit?

    Because durian was forged in the bowels of hell. Makes perfect sense

    It does and doesn't. The outer layer of the durian, yeah that's gone. Dense biomass presents a unique scenario though. Where steel is homogeneous, and conducts heat very well, cells are "hollow" and contain a lot of carbon. Water vaporizes. Proteins vaporize. Carbon burns off. Slightly deeper: water vaporizes. But there's no oxygen here. The burning biomass outside is consuming it and dumping carbon dioxide as it goes. What happens when carbon heats without oxygen? It purifies. Down to pure carbon. 3,630C to melt it away. What's more, it's not solid carbon. All that water and protein is long gone, but now it's empty space. Insulation. It's impressive how much biomass blocks heat.

    Time matters. Long enough, the outer layers start to burn away. Oxygen moves deeper, carbon burns, not melts. That layer burns off. Oxygen moves deeper. You didn't need 3000C. But you need time and air flow. If you're trying to see who between a mass of steel or an equal biomass gives up first, the steel will fail every time.

    This is actually one of the principles that is causing building codes to start accommodating load bearing timber in tall buildings. Even though wood is combustible, wood beams that are thick enough can withstand fire for long periods of time. They're still working out what the different tests and standards should be, but some jurisdictions have approved timber skyscrapers.

    Jet fuel can’t melt Durian fruit.

    An organic heat shield for spacecraft then.

    Has anyone here eaten durian? Is it more tolerable than the stories say?

    Smells like sewerage (which is why they're banned in most hotels, planes, transit and enclosed spaces where they're common), tastes like a fancy dessert. It's a complex flavour that's honestly unique, and they don't all taste the same - various sub-varieties exist.

    To me the most consistent flavour of them is a very creamy mild honeydew-melon and vanilla flavour, with a dash of banana. Very pleasantly floral and generally quite sweet.

    Given that description you'd think I'd love them but I actually can't stand the smell and look (bro the fruit flesh looks like yellow turds), I've only ever eaten them under duress haha.

    I've only had it once or twice. It kind of resembles a mango and a banana mixed in flavor. Maybe like 75% mango and 25% banana. I was quite fond of it, but unfortunately the stickiness afterwards was quite unpleasant and never came off no matter how much I washed.

    I grow up with durian, kinda depend on how well your tastebud like to be challenged, because it's not stink like smelly drain(that award goes to stinky tofu). Once you overcome the smell and the mushy texture it's full of unique flavour depend on the cultivar. It's probably the most unique fruit coming from south east asia, and SEA have a tons of unique fruits.
