    Thanks for watching super nerds! HUGE thanks to my good friend Allen Pan for his help on this -- definitely go subscribe to his channel if you want more stuff like this. And I hear you: do more of these kinds of videos! I'll try my best. Sometimes it's hard to get time/money/talent to come together, but I'll get some more going for you -- kH

    @Ran Wolf Yeah, that's what i want to know. I don't know effective, practically speaking, a lightsaber would be against wights since we have seen them able to move even with parts of the head missing. so you would have to carve them into little pieces. As for the walkers themselves they have shrugged off fire before. That said from what Because Science has talked about before a lightsaber is really, really hot.

    A theory I propose is that instead of simply freezing the metal maybe there's a form of physical and chemical change and the swords are being turned to water/ solid ice. That completely changes how the sword works. If we look at the show, the swords are shattering into ice...not frozen bits of metal.

    A bit off-topic, but I have read that photons can be emitted when an electron that has been excited (gained energy and moved into a higher electron shell) looses that energy and drops into its previous shell. If this is true, @Because Science, could you do such a thing to the electrons in a human to where the body will emit light similar to a lightbulb? If you could, then what would happen to the body?

    Mr Pink Iron is also pretty ductile so pure iron wouldnt shatter no matter what the walkers tried . If it was a piece of steel just heattreared and not tempered it would shatter .The thing is non tempered heattreated steep shatters even without freezing it because it too brittle. But yes copper and bronze would be very good for cold resistance and if titanium exist it would work too because it is muvh better in dealing with temperature changes compared to steel and iron.

    The idea of the resonance frequency idea for the shattering of the swords make very plausible sense given the way that the swords shatter. Though I have an additional theory to pair with this. When forging a sword, one of the most important processes is the heat treatment process. In a very high quality blade, we harden and temper the blade to make a very hard but resilient blade. However if it is not down right we leave stress points in the blade and make a brittle or malleable blade. Thus I think got smiths just don’t do a very good job at the heat treat or worse just harden their blades thus making them very brittle. Thus when hit by the white walkers, their strength and the low temperature just shatters the blade really easily.

    Allen's test was kinda flawed if I am thinking about it right. If the chilling of the blade happens when it hits the whitewalker' s sword then the sword would be going through thermal shock the same time as getting in a sword fight. Maybe thermal shock wouldn't matter in real life science with metals but if we are saying that the cold sword is like a magic heat sink then that with the force of the swing may lead to a shattered sword.

    The sword could have been poorly made with high inclusions of slag and carbon. It could have had too much carbon in it (1.6% or more by weight), making it white iron instead of steel. Then it would be brittle at room temperature.

    oh hey! i know why the sword shattered so easily at hardhome! ya see, they have a really bad habit of forging swords out of cast iron. it has so many bubbles and pits that it shatters on contact with pretty much anything. so a white walkers weapon, or WWW, wouldn't have to try very hard to do even worse. so really, maybe valerian steel is what we here call "regular steel" while westeros mistakenly refers to cast iron as steel.

    Hey Kyle! Newer watcher of the show. I was wondering several things while you were talking about the composition of the sword. Is it possible that what they call “steel” and “valerian steel” (never watched GoT) are just misnomers? Would something more akin to Iron, which is much weaker structurally than steel, could be what they call “steel” and ACTUAL steel is their so called “valerian steel”? Also, one thought has been lingering from Alan’s experiment: That sword may have been crappy, but it was made using modern methods with modern materials. It could be that the sword he used was just better than the older style forging. Maybe there’s a scene of someone forging their blades?

    Not 100% on this but like 90%. The test done for this doesn't seem to be credible, the liquid nitrogen and stuff I agree with (although that didn't look like an I beam), but he said that the sword was cheap and made from carbon steel (VAGUE). Between that and how it looks leads me to believe that it's S275(cheap and most common steel, in Europe anyway). Lower carbon content in steels cause it to be more ductile so... NO ONE IN THEIR RIGHT MIND WOULD MAKE A SWORD (to fight with) FROM THIS MATERIAL. Should have used a sword made from something like W2 (common sword and knife material with high carbon content) the higher the carbon content, the higher the hardness and the more brittle the sword will be. This has been an alcohol fuelled rant from a mechanical engineering student.

    The steel used for modern swords is "spring metal", flexible and hardy (they can witstand a lot of punishment); back in times like the medieval age (the time that GoT takes inspiration from) steel wasn't of that much quality, it's somethin people tend to forget, the steel we use ain't the steel our ancestors used, their steel was more frail, less pure and with other problematics, and that's why folding and differential tempering existed (that's why katanas have that that weird wavy thing).

    I don't think it would've shattered anyways, but you should've pulled it out after soaking for a few minutes and then smacked it on the beam immediately, not a minute later after it had time to warm back up a significant amount

    Isn’t modern steel (even crappy modern steel) still way better than steel they would have had in the past ? Maybe If the steel was made of iron it would shatter easier. In my experience this is true

    The reason why your "el cheapo from the internet" didn't shatter is probably because it's made of mild steel, a low-carbon steel which is quite ductile even when cryogenically cooled. A proper carbon tool steel which can take a good edge would be harder and more brittle when super-cooled.

    It’s not temperature but the vibrational frequency imparted from the white walker weapon to his opponent. Non valyrian steel swords have resonant frequencies which make them vulnerable to WW weapons. Think earthquakes vs non earthquake proof buildings.

    Well he was using a wildling sword so I would assume it would be pretty low carbon content maybe around .1%. I know some swords from the 11th-12th centurys have around that amount of carbon. Try redoing the test with a more correct steel. I would be curious to see if the outcome changes.

    If this was a cheap sword, it's likely what Shad from Shadiversity would call a sword-like object (SLO). They generally lack the distal tapering (decreasing the flat-to-flat distance when going from hilt to point) found on real swords. This bulkier geometry may reinforce the material.

    As just a bit of GoT lore info, the implications from the books are that Valyrian-steel was made using Dragon Fired Forges, using an alloy made up of Steel and Dragon Glass/Obsidian. Not something I think would work IRL. But it's book magic and well, that adds in a unknowable variable into the mix.

    A sword might not shatter even when that cold(even though the sword seemed to have heathed since he could hold it with one hand), however since it's "magic" and the sword is being freezed instantly, wouldn't the sudden change combined with a sudden hard blow make a difference?
