Sometimes I forget that Dan is a weapons expert, then he goes and pulls off a shot like that after an eloquent explanation of the bullet type and I’m reminded.
His tone changes from his usual jokey, to matter-of-fact explanation. He did the same thing during one involving explosives, rattled off a rather technical explanation of the process that was so out-of-character for what we normally see.
@@PacMonster0 I believe its actually more about the speed than anything else. Its about the principle of inertia, since the ball just cant accelerate fast enough to get out of the way of the bullet. Then ofc the bullet shatters because its its less hard.
@Zoddom Don't accidentally fall into the mindset of harder equals more better. Soft things don't shatter. Hard things shatter and crack. That's why the part of the ball that was attached to the strings of the first ball was breaking on impact, rather than the actual string. More than anything it was the difference in mass COMBINED with the hardness, than the speed of the bullet and it's inertia. This is also completely disregarding the fact that it's a sphere, which is pretty ideal for diffusing the force of the bullet as it only makes contact with a single point of the bearing, which puts a LOT of force internally on the bullet. Spheres are a REALLY good shape
If you shoot a lot you know how bullets explode when you shoot steel. The crazy thing is that a tiny bearing shattered the bullet and not a giant steel plate.
I sometimes forget than Dan was in the army and actually knows what he's talking about. Also that ball bearing had 4x less energy than than the 9mm but had a much better transfer of energy, it's not all about power on paper
Kinetic Energy = ½mv² The bullet itself weighs 7.5 grams, the steel balls weigh 28 grams each. That equation for calculating kinetic energy results in a value of 459'000J of energy for the bullet and a whopping 1'020'000J for each steel ball. The steel balls they fired through the air cannon had much more energy.
It'd be interesting to see what happens with a rifle round like a 5.56 or 7.62. 5.56 is designed to fragment to make a mess of your insides so I'd imagine much of the same as the 9mm, though with more energy to push the rest of the balls along. A 7.63 is more or less a solid mass meant to drill a hole through things.

@@jacoblansman8147 Um, you may want to check the math again. Remember it's ½mV² meaning the energy increases massively with the V not the m. The bullet travelling at roughly 3 times the speed, but 4 times less mass means roughly 3^2/4 or 2.25 times more energy in the bullet. Also, 1,000,000 J is a gigantic amount of energy, remember that J is calculated in kilograms not grams. Written out: Ball bearing: 270mph=120.7 m/s 1/2*0.028kg*120.7^2 = 204 J Bullet: 785mph = 350.9 m/s 1/2*0.0075kg*350.9^2 = 462 J It really is about better transfer of energy and especially transfer of momentum since it is a newton's cradle after all.

@@PacMonster0 I thought something like this might be an issue. Maybe a projectile of a lesser weight would help instead. I'm not sure. As you said, this is a very fine tuned object, so it would be tough to find, but must be someway of shooting it without immediately destroying it to the extent either
I love when Gav and Dan talk about things they're experts in. They do it so casually, but it's so much fun to watch, since they're so clueless otherwise.
It's why I love videos like this or the videos where they go insanely slow. My all-time favourite video on the channel is the pyrex explosion because of the insane amount of depth Gav goes into talking about slow motion.
I think it's great because he's so matter-of-fact about it, he changes from amiable test dummy/target to amiable explosives/firearms expert without even changing expression. I still can't get over his hand-to-eye coordination with that katana a few years ago.
The "insta-snap" of the first ball in the cradle is caused by something called *spallation* wherein-when a piece of metal is hit extremely hard-the energy will attempt to escape out of the metal in all directions, causing bits of the metal to fly off. This is a huge problem in tanks. A bullet hitting the outside can cause pieces of metal to fly off of the inside of the tank and injure the crew. Consequently tank armour has to be carefully designed and insulated from the crew by another layer of something.
@@TalesOfWar That mitigates the hit but doesn't change the possible energy transfer unless you are speaking of a composite liner inside the tank to catch the splinters
@@stephen1r2 I'm not a material scientist in anyway, but to my knowledge metals are crystalline, making me assume energy transfer would spread molecularly in all directions equally... I wonder if a different structure could direct the majority of the energy in a particular direction.
First World War tanks crews wore chain mail to protect from the all the tiny flecks of metal that flew off the inside when they were hit with machine gun fire. Tiny shards of fast moving hot metal, showering the inside. Not fun. Search for “splatter mask” they look scary.
I always thought that outer plate of armor are made as hard as possible with enough ductility on it to shatter the bullet and the inner armor are made of material with high tensile, compressive and shear strength to absorb as much kinetic energy as possible from the bullet fragments.
I love Gavin's so-easy-to-miss joke that he slides in at 11:23 right after Dan talks about how Newton would be "looking down on them" with pride. I see you, Gav.
@@chair6703 The well obscured humor is the clever usage of down as a homonym. As the story of Newton's interactions with gravity is, for the most part, assumed to be common knowledge, saying that Newton is looking "down" references that he a) is looking at them from heaven, which is usually associated with up and would enable him to look down, and b) was an instrumental physicist in unraveling the universal law of gravity. (This next part is not meant to insult, just covering my bases. Internet trolls and all) Also, in the off chance you DID get it and are making a joke, sarcasm/facetiousness doesn't translate well over text, especially without punctuation.

@@user-gx3ji2sj8n normally you would say "look down on us" as in, he is in heaven, looking down, but gav says it as if he is dead looking up from the grave
"He's looking down at us thinking 'yes boys.'" "He's definitely got a smile on his face as he looks up on us." Sounds like we have two opposing opinions on where Newton's at right now.
@@logicalChimp lol it sounded like up-on us to me, there was definitely a pause in between. You can even see him smirk a little right after saying it lol
Literally scroled down at 11:10 just as the outro was playing to start reading comments as usual, and I read your quotes EXACTLY in time as they were saying it.
@@avg345 Dan explicitly says it's FMJ, and it's certainly not hollow point. Doesn't look like a frangible round either. It was definitely an unexpected outcome, but it's understandable that a small dense ball of stainless steel could break a 9mm FMJ.
9:04 I really like how you can see the whole cradle kinda slightly stop in midair as the balls nylon strings no longer have slack and the force of both parts fight for a moment before giving way to the higher force.
I love that yall kept in the misses, showing the amount of skill and effort required to be that good of a shot. All the props in the world for making that shot
Dan said "Looking down on us" and I, knowing at least a couple of scandalous things about Isaac Newton, thought "Aw, that's a sweet sentiment, Dan." And then Gav. xD
Gav could just mean he’s looking up at us from his grave in the ground, which would be a non-theological perspective, rather than a judgement on the man’s moral character.
@@XREXP0 he was an NCO in the British Army, was in for quite a few years, although they don't mention it much. In the earlier videos there were always sets of them where Dan was "away" etc.
@@SlyTreeRat My Dad was a crack shot before he got drafted in the late 50s, the upper Brass was impressed enough to give him a spot driving the C.O. (some General at the time), around the base most of the time. I sure do miss him. He could hunt squirrel with a 6 shooter 22cal. A squirrel with each bullet. I know because I was his retriever 😏.
@@SlyTreeRat While true the but the chances of person being a good shot goes up tremendously if they have military backround when compared to an ordinary citizen, especially in Europe.
The first ball was hit SO hard that the welds gave way from the vibration. The second ball hardly moved but had a huge vibration force which wasn't enough to shear the welds clean off. The third, fourth, and fifth balls separated from their welds due to velocity to the best of my understanding. All in all this is a gorgeous example of physics in action.
If you liked this, check out the various air cannon videos on Smarter Every Day. There's some awesome slo-mo footage and that is a MUCH beefier cannon.
@@edwardcardona717 They could, but then you're back the wire just snapping. There is a lot of force being transferred into the cradle, it would take quite a bit of engineering to make a functioning cradle that doesn't either snap off the wire immediately or send the base flying off.
The bullet imparted less energy on the balls because it is made of softer metals that could not absorb the impact like a steel ball bearing. The shock on the bullet causes it to shatter, rather than transfer its energy. I would love to see this test repeated with a 5.56 green tip with the mild steel core. Keep in mind that Green tip is NOT armor piercing ammo because it is mild steel. All it does is retain its mass and shape when passing through a barrier.
Can we just take a moment to appreciate Gav's joke at the end about Sir Isaac looking up at them with a smile on his face? Dan either didn't catch it or ignored it, while Gavin stood there smiling proudly.
That low bounce into the table and upward deflection was a once in a million shot, especially as you got in on camera in slow mo. You probably couldn't have gotten a more fascinating shot if you had set out to try for it.
You guys are so entertaining. It's like being a mad scientist little kid again. Seriously, I was like a mad scientist little kid in the 1960s. So much fun!
@@speedstone4 (not a physicist, educated guess) the bottom of the base is compressed, then re-expands, and overextends, pushing it off the table. Additionally, the direct transfer of energy can only go through at the speed of sound in that material, so that's part of the delay.
Absolutely. These guys have been around since the early days on TH-cam been watching them for yearsss now. Always wholesome nostalgic fun to see them back together.
It was incredible to see the bullet fragments fly off then the steel balls go "oh right we should move". WILDLY good aim for all three shots Dan, you scary bro.
Amazing to see the bullet hits the cradle and flies off first and then the cradle does. The friction holding the cradle resisted motion for a while, gave up and then whoosh!
This would be really cool with a custom Newton's Cradle with much stronger wire! It seemed as if thats were its main point of failure was when hit with the BB
@@Reckless-mindfulness They're not trained to shoot at such small targets, they're taught to shoot at the torso. I think all his shots were impressively accurate.
The initial "ball" rounds had a very large amount of energy absorbed as evidenced by the cratered Newton's Cradle ball. Would be much more energy transferred with harder materials, like tungsten rather than mild steel. And . . the 9mil round was pretty intriguing to say the least. Nice Piece-O-Werk Boys ! ! A thought . . I've seen vids of car audio systems actually turn auto glass into a "wave over water" without breaking it . . slo mo worthy?
That the Newton's cradle ball was cratered is actually evidence that energy was transferred since it takes energy to deform the target. You are right to say that energy was absorbed by the target, but that energy could only be absorbed by the target if it had been transferred to the target.
I've seen car audio systems actually tear the factory body sheet metal on a vehicle before. It's pretty awesome that a sound system can destroy an automobile. Metal gets torn, glass breaks, holes end up in metal floors, dash boards and interior parts get blown apart, tail lights fall off, etc..
An expert indeed! Absolutely incredible. This is a perfect demonstration of collision types in physics. When using the ball bearings, because of their hardness and the hardness of the ones in the cradle, the collision was almost (but not entirely, as the pits on the balls show) elastic, with *most* of the kinetic energy being conserved, where the kinetic energy of the system afterwards was roughly comparable. If you calculated the energy of the balls afterwards, given their different speeds, it is roughly similar to the input energy. The softer and faster lead bullet on the other hand is entirely inelastic! Most of the kinetic energy of the bullet was either turned into heat through friction and shear forces, or deposited into the air and baseplate as the shards of the bullet sprayed out. The balls of the cradle, as the secondary object in the collision, maintained momentum and had some kinetic energy as a result, as did the cradle itself, but most of the energy was lost. You used a newtons cradle to demonstrate *inelastic* collisions. Physics professors will either adore you or despise you for this, but I'm positive Newton would have giggled after he stopped gawking at the concept of cameras that take photos, cameras that take so many photos it can play them quickly enough to convey motion, and cameras which take so many photos so quickly that they can capture motion faster than the speed of sound.
I mean to be fair, a slow motion camera taking a massive number of photographs of motion over a short period is a pretty good way to think about calculus (or fluxions as Newton originally wanted to call it)
I've never really taken a close look at how a Newton's cradle is constructed. But it seems that the interface between the ball and the string is a welded-on tube. I think what happened to that first one is that the impact sent a sort of ripple that caused the welded joint to fail.
Video Suggestion: Get a centrifuge (the kind used in labs to separate things in suspension), remove the housing/case, then film separating things at a frame rate where either each vial makes one rotation per frame, or where each frame captures the next vial at the exact same location, and see how various things separate in the centrifuge, in real time, as if it wasn't spinning at all.
I would have loved to see the experiment with ‘stronger’ Newton's cradles: maybe one with a large number of balls, or clamped down, and/or reinforced do that the frame doesn't get yeeted along.
I love how Gav couldn't contain his reaction when rewinding the footage. I know in the behind the scenes footage he mentioned that he tries not to digest anything that actually happened, but this time was just too much. Thanks for leaving that in.
Love how the cradle just sits there when the bullet goes through it, then POP it jumps off. Goes to show how much of a delay between action and reaction between the masses. Now see what happens when an armor piercing 556 hits it instead of the softer FMJ. That will be a sight to see, just make sure everyone is behind something.
Very interesting, especially how easy the piece that holds the wire snaps off of the ball bearings. Makes me wonder what would happen if that connection point was sturdier, and what would happen if the base of the cradle was clamped down.
Only when shot by an expert with a lucky first shot. As that newtons craddle is shoved right up your um hole it should spread out doing " less " damage.
9:50 The way the bullet just blasted itself apart when it hit the ball, it kind of reminds me in a way of when if you are high enough from water and you drop onto it you don’t fully sink immediately, the water acts like a solid and you smack into it then you sink, it’s kind of like that.
@@oksowhat Incorrect, that isnt surface tension , that is the density of the water, for example, a jump from 200 ft into seawater is more difficult to penetrate at the speeds attained than the same jump into freshwater, which has a different, lesser density.
I've always thought about this but have never said anything but, your guy's friendship above all else is a really cool thing to watch and be a part of. Thanks for all of the videos you have made over the years. Keep it up.
right? that made me stop and think for a second and realized it's the air disturbance that did it. the material absorbed the impact energy and shattered or vibrated slightly, but what made the apparatus move was the air pressure which took longer to propagate. this suddenly makes glass phone screen protectors make sense to me to a degree. they're cumbersome and ugly and still accumulate scratches, but they distribute impact and make the actual phone glass not take the hit.
I love the delayed reaction of the air pressure blowing everything away. But then there's a similar delayed reaction with the bullet and it's just mind-bending.
I would've guessed that the first string snapped because the smaller ball shot from the barrel hit the first ball at a point above the center which pushed the ball slightly downwards and thus snapping its strings off
@@MrBlaktoe i actually don't think it's the deformation nor the weight. I think it's due to the initial vibration of the impact combined with the existing tensile stress, which broke the weld as there many irregularities in a weld.. if it would have been due to the weight of the ball it would only have been the string that broke, and if it was due to the deformation the break would likely be at the base of the loop. I suppose you could argue a deformation is a part of a vibration in any case I have close to 0 confidence without doing the experiment myself. 😂
That outro with the exact timing for the sunset was awesome. That whole shot, you can see the Sun disappearing, until the last ~ 15 seconds. The video itself was super interesting, I imagined this behaviour would happen but not for the correct reasons. Thanks a lot!
You two are the very definition of "greater than the sum of your parts". I could have watched a one hour video of this and still wanted more. Any time Dan gets to be Smart Dan is such a treat, and Gav that was some incredible footage and sound design!
"If they were perfectly hard balls..." followed by that snicker was peak dude comedy. 10/10. I shouldn't be surprised that the bullet barely damaged the balls, but there's just something magical about seeing one of mankind's worst inventions failing so spectacularly against a single sphere. It's like something straight out of a science fiction movie.
I like how the string that attaches to the ball did not swing. Instead, the forward movement travelled all the way up the chord and you can see the elbow shape of the string. Also, from close up, the second ball, while not inheriting as much speed, looks like it has the largest flatspot.
However does the sound for you slomo-guys!! He or she is your rocking star. Your Diego’s would be like films of pre sound ages in theaters. Doing such a great job
I find it more impressive that Dan fired the round perfectly between the Newton's Cradle and the wood it was on! I love these things! So cooooooooooool!!!
@@stefthorman8548 Define "it." The projectile hit something 3 times. The front ball bearing got hit once, and the second ball bearing got hit twice. The remaining ball bearings were not contacted by the projectile in these frames. I think the fact the 2nd ball got hit twice is pretty interesting; the shot must have been lined up very well.
I wonder what the minds of those like Newton would think of the slowmo cameras and their capabilities. Curious to see what interesting things they'd want to see in slow motion.
Definitely! I wonder what sort of crazy things Newton would have tried if he'd've had access to a slo-mo cam. How much of our current history would be different due to things he may have possibly found?
I would like to see this exact same experiment but the balls on the Newton's cradle gradual go down in size( Projectile ---> Large to small) or other way around, until they are half or less the size of the projectile. Because they have to transfer energy but they are getting smaller in size to keep the consistent energy going they increase in speed to make up for weight weight loss and maintain kinetic energy. it would be interesting to see what happens to that final ball with how fast it may go. understandably the energy transfer isn't PERFECT it won't be a perfect "last ball goes twice as fast".

I love when Gav and Dan talk about things they're experts in. They do it so casually, but it's so much fun to watch, since they're so clueless otherwise.

@@5peciesunkn0wn but the first ball is a Prince Ruperts Drop.
Take this! th-cam.com/video/QfDoQwIAaXg/w-d-xo.html
The "insta-snap" of the first ball in the cradle is caused by something called *spallation* wherein-when a piece of metal is hit extremely hard-the energy will attempt to escape out of the metal in all directions, causing bits of the metal to fly off.
This is a huge problem in tanks. A bullet hitting the outside can cause pieces of metal to fly off of the inside of the tank and injure the crew. Consequently tank armour has to be carefully designed and insulated from the crew by another layer of something.
This is where composites and ceramics come in to play.
@@TalesOfWar That mitigates the hit but doesn't change the possible energy transfer unless you are speaking of a composite liner inside the tank to catch the splinters
@@stephen1r2 I'm not a material scientist in anyway, but to my knowledge metals are crystalline, making me assume energy transfer would spread molecularly in all directions equally... I wonder if a different structure could direct the majority of the energy in a particular direction.
First World War tanks crews wore chain mail to protect from the all the tiny flecks of metal that flew off the inside when they were hit with machine gun fire. Tiny shards of fast moving hot metal, showering the inside. Not fun.
Search for “splatter mask” they look scary.
I always thought that outer plate of armor are made as hard as possible with enough ductility on it to shatter the bullet and the inner armor are made of material with high tensile, compressive and shear strength to absorb as much kinetic energy as possible from the bullet fragments.

@@chair6703 The well obscured humor is the clever usage of down as a homonym. As the story of Newton's interactions with gravity is, for the most part, assumed to be common knowledge, saying that Newton is looking "down" references that he

b) was an instrumental physicist in unraveling the universal law of gravity.

The first ball was hit SO hard that the welds gave way from the vibration. The second ball hardly moved but had a huge vibration force which wasn't enough to shear the welds clean off. The third, fourth, and fifth balls separated from their welds due to velocity to the best of my understanding. All in all this is a gorgeous example of physics in action.
The bullet also grazes the second ball as it passes by, which probably slowed the ball down enough to not snap as it swung upward
Looks like string broke to me
The first ball was hit slightly above center so when the projectile hit it there was a downward force that snapped the string.
I think those are cast.

I'd like to see this with a Newton's Cradle that was secured by metal wire, to see the difference between the wire and the nylon.

@@maebon Maybe they could secure the base some way?
Fiber wire(braided fishing line) is stronger than steel of same dia.
@@edwardcardona717 They could, but then you're back the wire just snapping. There is a lot of force being transferred into the cradle, it would take quite a bit of engineering to make a functioning cradle that doesn't either snap off the wire immediately or send the base flying off.
@@maebon thats the whole point tho. to see if you can, and to see if theres any difference between the types of wire.
Wow, the second ball got hit three time (on camera). That has to be an incredibly aligned shot to stay on the exact same plane for that long.
The bullet imparted less energy on the balls because it is made of softer metals that could not absorb the impact like a steel ball bearing. The shock on the bullet causes it to shatter, rather than transfer its energy. I would love to see this test repeated with a 5.56 green tip with the mild steel core. Keep in mind that Green tip is NOT armor piercing ammo because it is mild steel. All it does is retain its mass and shape when passing through a barrier.

It’s crazy how “long” it takes for the cradle to move after being shot.

It must be the air flow following the bullet that pushes the cradle, not the bullet itself.
@@speedstone4 Probably the fiberboard is compressed, and then springs back.
@@HappyMonkeyYT that doesn't make sense to me. Whatever you mean by fiberboard, if it springs back, shouldn't it go in the opposite direction?
@@speedstone4 (not a physicist, educated guess) the bottom of the base is compressed, then re-expands, and overextends, pushing it off the table.
Additionally, the direct transfer of energy can only go through at the speed of sound in that material, so that's part of the delay.
it's so nice having the 2 of them together again

@JENNITA B.O Ooh, foreign language bots
It was incredible to see the bullet fragments fly off then the steel balls go "oh right we should move". WILDLY good aim for all three shots Dan, you scary bro.
And that's why the cow is spherical
I thought the same. Kinda awesome. I was taught the steel balls 'cant move out of the way fast enough' and something's gotta give.
Amazing to see the bullet hits the cradle and flies off first and then the cradle does. The friction holding the cradle resisted motion for a while, gave up and then whoosh!
This would be really cool with a custom Newton's Cradle with much stronger wire! It seemed as if thats were its main point of failure was when hit with the BB
the point of the newton's cradle is to have as light a wire as possible.
I thought the weak point was the connection. Most wires ripped off of the balls instead of breaking.
Get it done, #markrober
It's not the wires that broke first.
How impressive that shot was by Dan is not being appreciated enough!

@@Reckless-mindfulness They're not trained to shoot at such small targets, they're taught to shoot at the torso. I think all his shots were impressively accurate.

The initial "ball" rounds had a very large amount of energy absorbed as evidenced by the cratered Newton's Cradle ball. Would be much more energy transferred with harder materials, like tungsten rather than mild steel. And . . the 9mil round was pretty intriguing to say the least. Nice Piece-O-Werk Boys ! ! A thought . . I've seen vids of car audio systems actually turn auto glass into a "wave over water" without breaking it . . slo mo worthy?
That the Newton's cradle ball was cratered is actually evidence that energy was transferred since it takes energy to deform the target. You are right to say that energy was absorbed by the target, but that energy could only be absorbed by the target if it had been transferred to the target.
as someone who didnt finished school, this Is very worthy 👍
I've seen car audio systems actually tear the factory body sheet metal on a vehicle before. It's pretty awesome that a sound system can destroy an automobile. Metal gets torn, glass breaks, holes end up in metal floors, dash boards and interior parts get blown apart, tail lights fall off, etc..
You have accidentally achieved some of the best slo-mo footage of a ricochet I've ever seen
An expert indeed! Absolutely incredible. This is a perfect demonstration of collision types in physics. When using the ball bearings, because of their hardness and the hardness of the ones in the cradle, the collision was almost (but not entirely, as the pits on the balls show) elastic, with *most* of the kinetic energy being conserved, where the kinetic energy of the system afterwards was roughly comparable. If you calculated the energy of the balls afterwards, given their different speeds, it is roughly similar to the input energy. The softer and faster lead bullet on the other hand is entirely inelastic! Most of the kinetic energy of the bullet was either turned into heat through friction and shear forces, or deposited into the air and baseplate as the shards of the bullet sprayed out. The balls of the cradle, as the secondary object in the collision, maintained momentum and had some kinetic energy as a result, as did the cradle itself, but most of the energy was lost.
You used a newtons cradle to demonstrate *inelastic* collisions. Physics professors will either adore you or despise you for this, but I'm positive Newton would have giggled after he stopped gawking at the concept of cameras that take photos, cameras that take so many photos it can play them quickly enough to convey motion, and cameras which take so many photos so quickly that they can capture motion faster than the speed of sound.

I mean to be fair, a slow motion camera taking a massive number of photographs of motion over a short period is a pretty good way to think about calculus (or fluxions as Newton originally wanted to call it)
I've never really taken a close look at how a Newton's cradle is constructed. But it seems that the interface between the ball and the string is a welded-on tube. I think what happened to that first one is that the impact sent a sort of ripple that caused the welded joint to fail.
Video Suggestion: Get a centrifuge (the kind used in labs to separate things in suspension), remove the housing/case, then film separating things at a frame rate where either each vial makes one rotation per frame, or where each frame captures the next vial at the exact same location, and see how various things separate in the centrifuge, in real time, as if it wasn't spinning at all.
No, no, this is genius. I genuinely don’t know how this isn’t a popular comment. I hope you have a good day sir/ma’am!
Jesus that triple collision in the first shot was incredible.
I would have loved to see the experiment with ‘stronger’ Newton's cradles: maybe one with a large number of balls, or clamped down, and/or reinforced do that the frame doesn't get yeeted along.
I love how Gav couldn't contain his reaction when rewinding the footage. I know in the behind the scenes footage he mentioned that he tries not to digest anything that actually happened, but this time was just too much.
Thanks for leaving that in.
Love how the cradle just sits there when the bullet goes through it, then POP it jumps off. Goes to show how much of a delay between action and reaction between the masses. Now see what happens when an armor piercing 556 hits it instead of the softer FMJ. That will be a sight to see, just make sure everyone is behind something.
I think Edgerton is smiling down as well. Nice one guys.

Very interesting, especially how easy the piece that holds the wire snaps off of the ball bearings. Makes me wonder what would happen if that connection point was sturdier, and what would happen if the base of the cradle was clamped down.
Lots of energy, the structure would probably snap.

I love how when slowed down the bullet has gone off the screen and the cradle still hasn't moved from the energy of the impact!
right? that made me stop and think for a second and realized it's the air disturbance that did it. the material absorbed the impact energy and shattered or vibrated slightly, but what made the apparatus move was the air pressure which took longer to propagate.
this suddenly makes glass phone screen protectors make sense to me to a degree. they're cumbersome and ugly and still accumulate scratches, but they distribute impact and make the actual phone glass not take the hit.
It will never cease to amaze me that Dan is a weapons and ammunition expert
Astounded as always with the sound editing in the slow mo footage, well done with that
@Siatkarz shut
Im always impressed with the sound design especislly since i know he isnt a pro and he just figured it all out on his own
I also think it's going to be a mixture of both annihilation and sending the last ball up.
I love the delayed reaction of the air pressure blowing everything away. But then there's a similar delayed reaction with the bullet and it's just mind-bending.
And suddenly I'm spending my Saturday evening watching people shooting a newton's cradle 😅👌
the mass of the balls is too much compared to the string, that is why the foremost ball behaves as if there were no string attached to it
I would've guessed that the first string snapped because the smaller ball shot from the barrel hit the first ball at a point above the center which pushed the ball slightly downwards and thus snapping its strings off
You can see the intact hoop still attached to the string. The impact is snapping the weld right off the ball. Pretty neat!
@@Jikkuryuu bingo! more specifically, the ball is deforming and the weld is not so it just pops off.
no
@@MrBlaktoe i actually don't think it's the deformation nor the weight. I think it's due to the initial vibration of the impact combined with the existing tensile stress, which broke the weld as there many irregularities in a weld.. if it would have been due to the weight of the ball it would only have been the string that broke, and if it was due to the deformation the break would likely be at the base of the loop. I suppose you could argue a deformation is a part of a vibration in any case I have close to 0 confidence without doing the experiment myself. 😂

I would like to see this exact same experiment but the balls on the Newton's cradle gradual go down in size( Projectile ---> Large to small) or other way around, until they are half or less the size of the projectile.
Because they have to transfer energy but they are getting smaller in size to keep the consistent energy going they increase in speed to make up for weight weight loss and maintain kinetic energy. it would be interesting to see what happens to that final ball with how fast it may go. understandably the energy transfer isn't PERFECT it won't be a perfect "last ball goes twice as fast".
