It always surprises me that Dan is actually a properly trained weapons expert. He comes across as so goofy and aloof but as soon as sharp things or explosive things come out he is so serious about it

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.

Everyone that regularly shoots knows how difficult that shot is with a pistol even at 10yds. Seriously good shooting by dan

The bullet getting annihilated against the Newton's Cradle at 100,000 FPS was so epic and surprising and then all the force pushed it away.

It is always something to remember that Dan is not only a professional punching bag, but also a trained and highly specialized soldier.

Gavin trying not to laugh at Dan’s “if they were perfectly hard balls” at 2:46

Gavs knowledge of cameras and slow mo paired with Dan’s knowledge about weapons and ammunition is just the perfect combination. I always find myself admiring Dan’s know how and respect for weapons and explosives

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.

I love how it makes complete scientific sense why the bullet shattered, but it's still mind-boggling to actually see it happen.

You can always change the frame of reference and realize to the bullet's point of view it's being hit by five steel ball bearings that are traveling at the speed of sound.

Dan's marksmanship is really impressive. Most don't understand how hard it is to make that shot.

“I don’t know what I hit, I don’t think it was the balls, I think it was below the balls. - 8:27, favorite quote.

Never would have expected a jacketed lead bullet to shatter like that. Outstanding footage!

2:41 “If they were perfectly hard balls.. perfectly hard” Gav trying his hardest not to laugh and maintain his serious face killed me

I really liked watching the knot in the 4x4 redirect the bullet back up into the bottom of the cradle.

The "missed shots" from the bullets were great to see in slow mo, the way the wood split was awesome.

I can't believe how well you got that cradle lined up. Great video concept.

11:22 I love Gav’s smirk as he baits Dan with his “looks up on us” comment and Dan just missing it entirely 🤣

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’m so impressed with how accurate Dan is with a firearm, as well as safe, and respecting a dangerous apparatus 😊

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

Never get tired of Gav absolutely loving Dan's skill when it comes to his areas of expertise.

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!

I have a final exam tomorrow, in less than 10 hours. I am watching grown men shoot metal balls. Worth it

"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.

I've always loved how when Gavin wants an impossible shot Dan just goes, 'alright Bee,' and makes it happen. Such a perfect pair.

You have accidentally achieved some of the best slo-mo footage of a ricochet I've ever seen

3:38 I would like to point out that: The Newton's Cradle Balls are so hard and dense, it dented the ball from the cannon

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.

Do I understand why the bullet shattered? Yes. Was it still totally surprising? Yes. Well done!

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.

That was amazing the way the bullet disintegrated when it hit the ball!

"he's definitely got a smile on his face as he looks UP at us" *smiles at the table* I see you Gav! 😂

Something else to consider: the BALL bearings are, well, balls. That continuous curve also deflects energy remarkably well unless the bullet hits it straight on. That's the same concept tank designers were starting to catch on to as early as 1917.

Jesus that triple collision in the first shot was incredible.

And suddenly I'm spending my Saturday evening watching people shooting a newton's cradle 😅👌

I'd love to see this done with an armor penetrating round or a steel bullet. Something hard. I wanna see that interaction.

I absolutely love when Dan brings out the guns. I'm not a gun nut, but I could listen to him talk about them for hours

Incredible video! I most enjoyed the FUN the two of you experienced with the unexpected bullet outcome. Helluva shot, indeed. Bravo!

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 never wondered what would happen if you shot Newton's cradle but here we are

This is what I love about the pairing of Dan and Gav- Dan the weapons/explosives expert with knowledge and experience about cool toys and stories from his time in the army, and Gav the photography expert, who thinks up ways to have fun with those toys and knowledge, and then film it so they can watch it over again! Just two kids having fun!

I Love the videos you guys make. Each one showcases how beautiful our world is and that sometimes it takes a different perspective to be reminded. Thank you guys

Nobody noticed when Gav said "He looks UP on us" 😂😂

I would love to see this done with a Newtons cradle that has stronger string and connectors

11:22 I love Gav's subtle "he's got a smile on his face as he looks _up_ on us" 😂

This was cool :p I love that they're still finding creative things to slow-mo xD

Great to see you making this sort of content together again 👍 Keep it up.

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.

“Great shot kid! That was one in a million!” No seriously. That was one helluva shot by Dan, and I’m blown away by the results. Awesome vid!

I love these videos so much. This makes me want to make a reinforced newton's cradle to see what would happen if they didn't detach from their strings.

Dan is almost certainly the best non-guntuber shooter on the platform.

I love how you guys perfectly walk the line between faffing about and genuinely caring about the science, all these years later.

Can we just take a minute to GREATLY appreciate the fact that he just literally hit a dime!!!! I'd like to see what would happen if the cradle was secured to the surface so only the balls take the energy transfer along with an armor piercing or Full metal jacket round

Normally i couldn't keep watching a video over 2 minutes, but this channel guys, these videos i didn't get bored.

9:49 is probably the coolest thing I have EVER seen on UKposts. Dan's reaction is priceless.

That was incredibly satisfying to watch

It will never cease to amaze me that Dan is a weapons and ammunition expert

Newton's 4th law of motion: nothing escapes Gav & Dan capturing these epic moments on slow motion film for us all to enjoy

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

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.

I'm glad you guys include firearms in your videos. Their not scary death machines. It's all about the person handling it. I must say, much respect from a simple southern boy who enjoys the freedoms that were passed down to us from our founders. Isn't it great we kicked you brits butts back then? You wouldn't be able to do this otherwise almost anywhere else in the world! Much love from North Carolina!

02:56 what i found amazing is that the string of the first sphere instantly rips off after the impact

This is the most satisfying slomo guys video in ages, with the guys back together, outside, firing stuff out of a big cannon.

Conclusion: To protect yourself from bullets, carry a Newton's cradle.

These are some of the most satisfying shooting videos I've ever seen. Thanks!

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.

2:12 Small ball bearing 4:55 Same size ball bearing 7:55 Gunshot attempt 1 8:25 Gunshot attempt 2 9:13 Gunshot attempt 3

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.

AMAZING... well done guys!

The force is linear out of the barrel, and according to Newton, the "direction of motion continues until..." so the balls tend to "continue" propagation of the original force, and only smaller amount of effect from gravity, the nylon string, and impact/transfer of energy/motion and overcoming the inertia of the balls at rest are observed. They are the smallest affect to the original force (of the moving/fired ball). Quite a lot of information to see in these samples/sets of video data. Bravo!

Isaac: "Yes bois"

Freakin' Awesome, everytime I see the bois back together i get alittle misty eyed.

That 9mm shot into the ball was freaking awesome.. So glad I found your channel

Ребята, вы великолепны! Вы показываете ту самую физику на практике, которая так радикальна в теории)

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

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.

This channel is underrated :) Its just a blast watching these guys working what they clearly love doing.

Dan's military experience coming to bring an interesting piece to the vid. I dont think a single person watching this wouldve expected the bullet to *shatter on impact*

It's amazing how often the fail shots are just as fascinating as the ones where they achieve their goal!

it's so nice having the 2 of them together again

the wave developing on the last string is pretty neat!

This is the channel UKposts does not recommend me, but I search on purpose when I’m bored at 3am, don’t tell me to go sleep

How impressive that shot was by Dan is not being appreciated enough!

You guys perfectly captured that sunset. The ball bearing thing was cool too

WOW! Amazing shot and incredible footage!

I've heard that musket wounds were horrifyingly grotesque even though they don't travel as fast as modern bullets. This goes a long way to illustrate why.

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.

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.

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!

I'd love to see this with a significantly stronger cradle. Stronger structure and string just to see what would happen

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.

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.

I love that you can see the time delay of the elastic response of the balls and the waves propagating up the strings.

Probably the coolest video you guys have done.

"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.

Place 5 steel balls on a level surface, magnetize them slightly so they stick to each other very slightly and then repeat the experiment

I think Edgerton is smiling down as well. Nice one guys.

These two will forever be iconic

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.
