Rest assured, there are more than enough myths for this show to have run for another 100 years, although not all of them were truly urban myths. Some were more general misconceptions instead of a specific story but those were rare. Adam Savage has a YT channel where he talks about everything MythBusters in Q&A's. He might've mentioned this.

I personally Guss the reason why it’s hard to reproduce is that Volvo did recall some parts, they were one of the first one to use that technology and they seemingly got it wrong in the first batch but fixed it really fast so it might be impossible to reproduce without the right parts. A other issue could be that the car in question was on fire for some time in a relatively cold environment and the part in question got only intermittent hot wich caused the gas to gradually increase in temperature without compromising on the inner working parts.

23:23 Sadly, the fire extinguisher from the firefighters is what cased the bumper's shock absorbers to blow at that specific time. When you have a hot, pressure vessel under high pressure, suddenly cooling it down will rapidly shrink it and thus get its pressure even higher. This is a potential problem with military machine guns when they get too hot under sustained fire. The cartridges will get super hot, the pressure will be really high inside them, and if you pour water, or even cold air on or into the gun it can cause the walls of a cartridge to suddenly shrink, quite significantly, thus suddenly increasing its pressure, thus prompting an accidental discharge. This is especially a problem on a light strike or a defective primer. In the case of a belt-fed machine gun, opening the cover and attempting to extract the cartridge can be enough for it to suddenly cook-off.

Thoughts on the arrows. The horse adds about 30% extra speed, resulting in about 30% extra penetrative power. If the target is armored, these 30% can suddenly mean the difference between barely penetrating the armor and penetrating the armor AND getting deep behind it. Mongol invasion happened in the 1200s, when mail armor was used - arrows could shoot through it, but it certainly wasn't easy, you needed the correct arrowhead and actual war bow. 30% extra power from a horse could suddenly change a lot. In 1500s, it's more tricky, plate armor (helmets and breastplates) was pretty much inpenetrable for arrows. Leg and arm plates could, however, be vulnerable, since they were often below 1mm thick. 30% extra from a horse could, again, make some difference there, but you probably wouldn't aim for legs or arms from a horse.

@jarrodbright5231 20 сағат бұрын

You're thinking of using a full sized war bow from horseback? That would certainly look comical. And tha'ts kind of the point with this one. Hungarian horse archers used short compound bows. These are much smaller than an infrantry bow (war bow, longbow or crossbow), with a lower draw weight, and so aren't as powerful when fired from a standing position. The source of the saying or "myth" here is this is why the Hungarian nobles would claim the smaller horse bows were just as effective as the larger infantry bows. It wasn't about being literally "twice" as powerful when fired from horseback but that they were just as powerful as an infrantry bow when they're fired from horseback if not more powerful. And that extra momentum did in fact make a big difference - and the 30% increase in penetration was actually from an increase of around 70% in power, so it's actually a lot closer to proving the "myth" when you look at energy rather than penetration. Not claiming they got it wrong, just saying the Hungarians weren't exaggerating as much as it might first seem. If anything they set this one up further in favor of the horse archer than reality would because historical Hungarian bows would have been more powerful than the ones the demonstration riders were using and the Hungarian ponies wouldn't have been as fast as their horses were.

Nope, that is actually not their mistake there. But using modern ultra light, high speed carbon fiber arrows (>300 fps of >200mph) and a modern crossbow is. Medieval arrows were much, much heavier and shot from a medieval bow made from wooden or a composite horse bow made from horn, were much slower (arround 150 fps or 100mph) as well. Increasing the speed of these arrows by 40 miles per hour actually gave them relatively much more punch. Depends a littlebit on the used bow an typ of the arrow tip, but that myth is absolutly true.

@jarrodbright5231 20 сағат бұрын

@@JohnSmith-wg7nb They set the crossbow to replicate the draw weight of the bows the horse archers were using which looked to be significantly lower draw weight than the traditional compound bows. Also the horses they used were significantly faster than Hungarian ponies. I'm sorry but they set it up further in favor of the horse archers than was historically accurate. I would say the biggest issue was the conclusion: a 70% increase in kinetic energy is pretty close to "hitting twice as hard". Still "busted" but also pretty close.

Yes, it depends on different things like arrow tip design, material of the shaft, does the arrow hit a bow etc, etc. The real Problem is something else: They just f***ed up the whole archer myth completely here, lets break down why. The formular for kinetic energy is: E = m * v² / 2 Energy = mass * speed² / 2 Lets take an example: 1 kg * 50 m/s² / 2 = 1250 Joule Now lets double the speed: 1 kg + 100 m/s² / 2 = 5000 Joule Now we have established the fact that the increase of speed doesn't result in a linear, but exponential increase of penetration.

To achieve twice the amount of penetration by shooting an arrow while moving forward, you would need to drive at approximately 0.414 times the arrow's standstill shooting speed. This means if the arrow's speed when shot from standstill is 100 km/h, you would need to drive at about 41.4 km/h in the same direction to double the penetration power.

The glass didn't melt, it went above its "glass transition temperature". 1000°C is probably enough for that outcome, no need for 1400. Also if you shoot a crossbow, the additionol speed of the horse won't change as much cause you shot with a fucking crossbow, not a bow which shoots far slower. Also if you shoot through some clothes, the difference might actually double the penetration cause you need to get past a certain threshold. Kinda fucked up the science part in this episode.
