Machine Gun vs. Tree - Mythbusters - S04 EP29 - Science Documentary

[@TheLastPhoen1x]

Sharpened stick "plugs" the wound, arrowhead leaves a "channel" for the animal to bleed out... out of, plus it lodges into the flesh with the barbed ends and can do even more damage as animal moves rather than just fall out.

[@peterzerfass4609]

I love the 'shaker'. Crude, simple,...and yet elegantly effective.

[@dmaniar007]

Arrowhead has the advantage of damage overtime, especially if target keeps moving! A stick will most likely block the hole it created!

[@christianellegaard7120]

There is also the point that the flints could probably be re-used a lot more times than the stick. So, once you spent the time on them, you had them for a long time.

I think the other big factor for stone arrow heads is the longevity of them. A stone tip could in theory outlast multiple arrows. A pointy stick would easily become a dull stick after hitting a target. In the show none of the targets used had bones. I’d say that shooting an animal with an arrow with a sharp stick would lead to the end being dulled. Even if you could pull the arrow out and reuse it, chances are after 2-3 hits it would be too dull to use. You’d have to sharpen the arrow again and lose some length in the process. With a stone head that arrow could probably sail through dozens if not hundreds of targets. If the arrow breaks you can remove the head of the arrow and attach it to another shaft. Bones aren’t the only hard surface either. If you miss the target and hit a tree or a rock you’ll mess up a wooden tip arrow immediately. A stone tip may still be useful afterwards. All and all even if you say that it takes minute to sharpen a stick to a point vs an hour to get a stone arrowhead. If after an hour of work I can hunt/kill 30-60 targets before having to replace the tip vs 2-4 targets before having to sharpen a wooden tip then the effort is worth it. Plus some arrows may not have been used for hunting. Depending on the age of the heads they may have been used in combat. Early armour could have been good enough to stop a wooden arrow but not a stone tipped arrow. I could be wrong but I feel like the longevity and reusability of stone tipped arrows is why we see so many of them. But as they mentioned in the episode… we are only finding the arrow tips… who’s to say that stone tipped arrows were the norm… they could have only accounted for 10% of the arrows used. The rest might have been wooden tips.

[@daftwulli6145]

yea no stone tips are pretty brittle, there is a reason people don´t make swords out of stone, and even just daggers you would fine cutting knives but not daggers for sticking people.

[@xcoder1122]

@@daftwulli6145 Swords hit other swords or extra hardened shields. So stone hitting stone would be more brittle than iron hitting iron but stone hitting flesh is not a problem, as stone knives can be used for years to cut through flesh. Only a direct bone hit could cause an arrow head to break and those are very rare in practice. Claiming those arrow heads are too brittle is a very funny argument, considering that we still find them intact after they have been actively in use and buried for so many centuries.

[@daftwulli6145]

@@xcoder1122 Quote :" So stone hitting stone would be more brittle than iron hitting iron but stone hitting flesh is not a problem, as stone knives can be used for years to cut through flesh." 1, animals also have bones and hitting those is a big problem for stone, and no hitting bones is not rare at all. The whole chest area (you know where heart and lungs are, the things you want to hit) is one bone next to the other. So no, they are not rare at all, and I have no idea why you would think that. 2. nice try i already said cutting is not the problem, stabbing is. Try it yourself. You don´t have to make a full stone knife, just something thin enough and roughly the same shape. Quote :"Claiming those arrow heads are too brittle is a very funny argument, considering that we still find them intact after they have been actively in use and buried for so many centuries." 1. you find them since they are easy to lose, just like coins, something else we find all the time. And arrowheads have been used for far longer then coins. 2. another reason you find them is that during a hunt they probably did not have opportunity to collect missed shots since they had to follow the animal. THe rest of the arrow would be gone after a few ceades or at most centuries, but the arrowhead remains for much longer. 3. as for why you don´t find broken ones, they would not just break into 2 halves but many smaller pieces, you would no longer recognize. That is simply how that kind of stone usually breaks. Making something out of that kind of stone requires a lot of knowledge and patience since you have to hit the stone just right to not end up with many small pieces. 4. as for why they do not break in the ground, pretty simple : different materials have different traits. Stone can take quite a lot of pressure, so being burried under ground is no problem. But bending is another matter, try to bend stone and it breaks, and when it hits bone it wants to bend. KInda the same reason we combine steel and concrete they both can handle different kinds of forces very well, and support each others weakpoints (steel is strong where concrete is weak and vice versa)

[@bunzeebear2973]

Don't forget the wooden knives

[@MrMarinus18]

I also think with the arrows you have to consider the importance of the first shot. While you might carry multiple arrows you only get 1 first shot from stealth and that first shot will have to do enough damage to cripple the animal. So maybe they carried a handful of flint headed arrows for the first shot and then a larger number of sharpened stick arrows for subsequent firing.

[@HappyBeezerStudios]

Good point. And you want your shot to be successful, because if the animal keeps running away, you'll lose your flint head.

[@christianellegaard7120]

There is also the point that the flints could probably be re-used a lot more times than the stick. So, once you spent the time on them, you had them for a long time.

[@MrMarinus18]

@@HappyBeezerStudios No, stalking an animal is a very time consuming thing and getting close enough to get within shooting distance is very difficult. If the animal escapes with only a minor wound you have wasted a lot of time and energy for nothing. If you manage to sneak up on an animal you want your first shot to do enough damage so that it can't get too far. Sort of the same reason why shotguns are preferred for hunting as rifles often don't do enough damage in one shot to bring an animal down immediately.

[@HappyBeezerStudios]

@@MrMarinus18 that's what I said. The shot has to hit, because otherwise it would be an immense waste of time and work. If the animal runs, you wasted the arrow and the time to sneak up on it. So a deadly (successful) flint head is worth using over a wooden point that only causes a minor injury.

[@MrMarinus18]

@@HappyBeezerStudios A single arrow won't kill a large animal like an antilope or deer. What you are hoping for is to cause enough damage so that it won't get too far. Remember we are not talking about a deer slug that can fill an animal in one hit.

Back in the mid 80's I was an ARMY cadet in Australia. We went on a lot of different training camps. One of those was marksmanship training. We used 2 big trees with targets on them then fired only 2 rounds each out of an Armalite rifle( M 16) & both trees went down. There were only 20 of us and they were really big trees. Approx 1.5 metres wide & deep. The first tree went down & our CO let a few of us rip into the second to see what would happen. Didn't take long to fell the 2nd tree. I was so glad to see this episode, because I knew it would work. Also the ammo we were using was very small compared to what they use in this show. It just took a lot longer to do.

[@mirandahotspring4019]

When you take into account that arrow wounds kill by blood loss, a wider slicing point would cause a bigger wound with a better chance of slicing through a blood vessel. I mean bow hunters today use broadheads, not field points for that exact reason. It doesn't kill immediately and as the animal keeps moving it keeps cutting and has a wound channel for the blood to flow out whereas a pointed one blocks the wound. The eye black is dubious, no other sportsperson I know of in the world uses it, only in the USA. You'd think if it was that good cricket players would also be using it.

The arrow is also less likely to come loose when the animal flees, meaning it wiggles around in the wound does more damage. The pointy stick is easier to remove by accident by biting/pulling at it.

[@YoutubeWatcher264]

Regarding the arrow, they didn't test reusability, longevity, cleanability. People don't just use a tool because it is hitech, it needs to fulfill something else.

The name 'Denim; originated some time ago in the early part of the 20th century from a canvas like material dyed blue which was produced by a small factory in southern France, this canvas like material was found to be very suitable for the manufacture of work clothes as it was very hard wearing, the factory was located at a town in France called Nim and the product was known as 'Serge De Nim', serge was French for cloth so the meaning was 'cloth of Nim'. The 'material was exported to other countries such as the US and the word 'serge; was dropped leaving just the words De Nim or Denim

[@larryclemens1850]

The larger wound of the stone arrowhead may be sufficient to warrent its use. An only shaft arrowhead may seal up around the wound which may be enough for the animal to escape to an area where it may be unrecoverable, like the middle of a lake, or a ledge on a cliff. Another factor that makes bleed out rate significant is if instead of fleeing, the animal decides to fight.

[@davidbakker-wester113]

Sharpened stick can fall out. A barbed arrowhead stays in the wound and keeps adding dammage.

[@ChristopherAdams-tl3me]

I think that the main difference between the two was how fast they bleed out and how easy it is to track if it's wounded because if you cannot find it you don't eat

[@PaulThatcher-iu5in]

There are several accounts of battles in the US Civil War where trees were felled in prolonged intense close-range shooting - and don't forget, many troops were still shooting minié ball shot, not rifles. Size of tree not recorded, but not brushwood, that's for sure. On the flint tip -v- sharpened stick debate: yes,making the flint head took ten times longer than sharpening the stick, but 2 factors may diminish this ratio: 1. the reusability of flint, 2. in both cases, a long, straight shaft has to be made, and as this is not a short job,the ratio of total production time, ie (make shaft + make head) to (make shaft + sharpen), should fall, and will be less than 10:1.

[@ryanrodrigues5355]

Isn't the arrow being "front-heavy" important for shooting at long range to ensure it arrives tip-first over longer distances? So with the arrowhead, not only can you do more damage, but you decrease the risk of doing NO damage (because the arrow tumbled and the shaft just doinked off the target). That's what thought anyways

[@coljaschoppe8670]

That's right, the tip should be the heaviest! You can see how bad it is without the tip if you shoot without the feathers at the end (they stabilize the arrow by slowing it down in the air and pulling it straight). Depending on the animal and the strength of the bow, the point could be even bigger. What you don't want is for the arrow to simply fly all the way through, but to transfer as much of its energy as possible to the body through damage. And anyone who thinks the wound channel is not so important is certainly not a hunter!😋 😉

There was a similar plot in the second Die Hard movie where the plane was leaking fuel and Bruce Willis tossed a lighter. But I doubt that would have worked because first off, the plane would be going too fast for the flame to catch up, and second, the blast from the engines would have extinguished any flame trying to catch up. And if you really wanted to get technical, if the flames did reach the plane, unlike gunpowder which has its own source of oxygen, it would have done nothing more than start a fire at the wing. The flames would not have entered the fuel tanks and there would have been no explosion. But it was still a good movie and I did enjoy it.

[@PanthereaLeonis]

They also tested how gasoline, diesel and jetfuel burns, and only the gasoline would actually burn if put down in liquid form, even when blasted with a blowtorch. I don't know what sort of fuel the Die Hard plane was using, but I figure the chances aren't very good that it'd even burn like that.

[@paparoysworkshop]

@@PanthereaLeonis I'm sure while making that movie, what we saw spilling out of the plane's tanks was just water. They're not going to really spill fuel out of a plane. As far as the line of burning fuel, most likely it is kerosine as that is fairly safe to use. But I'm not an expert, of course. Just my opinion.

[@PanthereaLeonis]

@@paparoysworkshop OH for sure! No they wouldn't actually spill the airplane fuel! I'm just guessing that real airplane fuel might not burn very well.

[@deydreamer]

I think a good reasoning is probably back then they had random sticks off a tree that are not arrow straight. It's likely very time consuming to make a straight shaft vs just finishing the end of a mass-produced stick, so arrowheads will extend the life of the arrow.

[@patlab555]

For the arrow test they forgot the most important in their "ballistic gel"... Bones! Flint headed arrows is to pass thru bones to reach the heart or any other vital organs like the liver, the brain, whatnot, when most only sharpened sticks will just ricochet, stop, break or get dull immediately. There is another important factor, the flint headed arrow will cut veins and arteries leading to important bleeding, thus easy to follow once the flint is inside as its shape will keep it inside making more damage when the animal is moving. With just a sharpened stick you will cut nothing as veins and arteries will roll on the stick's edges and the flesh will naturally compress around the wood, thus very poor external bleeding if none, very hard to follow as the injured animal has a lot more chance to run away way faster without getting weak for a while because it is not bleeding fast.

[@MadHax-wt5tl]

Another reason cavemen spent so long making flint arrow heads, it's not like they had anything else to do with their time. After all it was still going to be several thousand years before they started making this show, before that, nothing but arrow head carving time.

The one thing they missed with the arrow test is the difference in actual killing power. Need a shock sensor for lb/ft. That's what kills you. The chances of hitting an artery or vein is almost zero.

Okay the fault with the experiment on arrows is the feathered rear. Chances are good that first arrows did not have feather rears. Just naked stick.

We made spears out of the heavy end of a fairly straight stick. No flint in my area, just granite & basalt.

Animals run when they got hit so while moving the simple wood arrow can easlie wiggle out and making less damgange inside the body. The arrow with the stone tip will stuck mostly in the animal while it runs and as the animal move the sharp stone will damange more inside of the animal and more blood also easier to track and find it again.
