I cannot emphasize enough how nice it is that you haven't become one of those "shouty" channels for 12 yo's. And also delivers great content with a perfect mix of guesstimations, science, humor and slow motion.
I've been following the channel ever since I first saw the red water baloon a decade ago and I have to say...my now 14 year old son watched this video with me and enjoyed it just as much as I did. I think their way of presentation hasn't changed since then, aside from that Hollywood production series they did once...which was also nice because we got many videos in a short timeframe, but they weren't as interesting as the "i shoot or explode something in a quarry and you film it" or "i throw something at you or you drop onto something and i film it" video which they are best at in my opinion. =)
My thoughts too. As someone who shoots alot, i was super impressed how Dan managed to skip the bullets so consistently without hitting the glass. Good job Dan!
the dude's proven his free aiming skills are world class on this channel many times. I think Peter's right and the gun was mounted this time but wouldn't be all that surprised if that wasn't the case.
I don’t think we spend enough time appreciating the accuracy that Dan has in a lot of these videos. The fact that he can make these things happen conjoined with Gavin’s skill behind the camera creates some absolutely phenomenal content
@@RandomCarrot2806 I constantly wonder to myself how often Dan's expertise was the origin of a video concept. Because it allows for some spectacles that I doubt Gav and some other normal civilian derp could come up with.
WOW! I think the tank didn't break because when bullet hit the glass, it curved creating a vacuum behind it, and with the help of atmospheric pressure from the other side, pushed the glass back in place not allowing it to curve too much to break! COOL! We should use water in bullet proof glass!
Yes! I think that is it! If you pay attention there is a white film on the glass the moment the bullet hit like a pocket of "air"... Similar to when those pistol shrimps create negative pressure underwater! Also, hi Mehdi!
Wtf, I was literally too thinking about atmospheric pressure behind the glass! The faster the bullet, the more pressure because the air particles has less time to escape, but also the water is much thicker so the bullet needs to be faster. It's multi-variable function that's all not in favor for the bullet so a super-forecful one is needed to bypass the "threshold" where it breaks, or like Dan suggested, just shoot at a less steep angle.
We both have different answer and wonder which one is right... I think it didn't break because the water absorbed the impact and vibration right after the bullet hit so all the energy was transfert through the water right away instead of spreading through the glass entirely. edit: come to think of it i think the answer is a mix of both 😂
@@jamesclark4he is a former lance corporal and an explosives and ammunitions expert… he has quite a lot of professional experience mate. So fug off ya silly wanker. Cheers 😊
Could you please break this down and help me understand why the glass didn't break? What forces were at play to keep the glass in one piece? Does it have to do with the vacuum created by the bullet/impact of the glass and the atmospheric outside the tank? I've seen a lot of different theories and I would love to know what you think is going on.
Agreed. I like the professionalism. The "loaded, made ready, bang!, safe" callouts are reassuring, plus Dan's marine and munitions training is solid, thus the absurd aim and deep explosives knowledge.
I think this is the first time Dan & Gav fully went in expecting to break something, and ended up never actually breaking anything! Also I gotta say, the tracer round looked phenomenal in slow-mo.
@@jedimoody5294 no, stick with the 9mm, and walk the shots towards the back of the tank inch by inch until it breaks. Find out exactly how big the tanks health bar is!
I'm sure Gav was a little disappointed at first when the tank didn't break after firing the 9mm round - but the outcome was way better then anticipated. =)
I'm so glad Dan is back. Don't get me wrong, I love the material, I love Gav, but their friendship makes the show. They're wholesome AF and it makes my day better every time I watch them.
You have to appreciate how much this format could have been adapted or sold to a big streaming service (to be fair they did do a RU-vid Red thing) yet it is still what it was in the beginning. Two blokes having a good time doing crazy slomo stuff
They have 14 million subs.... they probably make significantly more than any network would give them while allowing them the sovereignty they are used to in their own channel.
One thing I love about this channel is how Gav & Dan always seem so genuinely amazed and excited by the footage they produce. You'd think after as many years as they've been doing this, they would sort have "seen it all" by now. I guess that's how you can tell someone has real passion for something.
i love how at the beginning they were worried the tank would be one and done but by the end they were marveling at how many takes they were able to get lol
what I (re)learned from this is that Dan is an incredible crackshot. At an angle that acute, for him to perfectly fire so close to the front and not once hit the sandbag or tip of the front part of the tank, is incredible.
@@K1VV1939 🤣🤣 you are right. I read the comments first and expected a much more impressive situation. You can train someone with zero firearms training to make that shot in less than an hour
Most likely mounted in a vise specifically for shooting. Would be nice to see the guns used. A bit annoying that seeing how different types of firearms can affect ballistics.
This is one of my favorites of all the videos you have put out. Fantastic shooting, both with the weapon and with the camera. Thrilled to see such excellent results! Thank you for the time and effort you both put in for this channel, and Dan, for the physical pain you have endured in many a video.
Hearing Gavin's surprise and knowing we were in for a treat was exciting, and while there are many times I've been shocked by one of your videos - _this one absolutely left my jaw on the floor with that bounce._
i haven't seen any great video for years ... i came here to see bullets in slow mo, but ended up leaving with headache that was caused due the extreme and constant YAPPING on a video that is suppose to show just bullet skipping over water in slow motion. they waste 14 minutes on a video that can be shown in less than 3 minutes with absolutely no words. their channel should be called dan and gav's yapping fest. i used to like their videos, but i unsubbed around the time they turned it into a yapping fest
@@SethiozProject Bye!! 👋 And the channel is literally called the Slow Mo GUYS, which by their own description is because it's as much about spending time with them and their "yapping" as it is with the footage. Off you trot.
@@leecudmore-ray6697 so just because my comment "goes on for a paragraph" then it must mean it's wrong? .. get off your scrubby phone and learn to write on keyboard. comments like that only take me 1-2 mins on keyboard to write, while some phone scrubber like you, probably spent 10 minutes on wring one small sentence and all it includes, is some childish "LOL" followed by hate. good job kid, is that all your primitive brain was able to come up with or did your granny help with other half of your comment?
These videos have such a timeless feel about them. This could have come out 5 years ago and the only differences would be the picture quality and your hairstyles. It's like all the technical aspects are constantly improving, but the content still has that same old charm :)
I think that might actually be on purpose, or something they take advantage of. I've heard Gav say that since he lives in TX and Dan lives in the UK, they maximize their visits by shooting multiple stunts all in a short period and then spacing the video releases until their next visit. I think the clips tend to be months old rather than years, but still neat
@@ThexImperfectionist I think that might be part of it, on a negative side: I've heard they've gotten backlash when they attempt to change some things so I'd understand if they feel apprehensive about experimenting. That said, I did notice some changes in this episode in particular. For lack of a better word, this one seemed to have cut some of the "behind the scenes" stuff and focused more on the "content" so-to-speak. And almost to back up my first paragraph: I don't like it lmao xD
As the bullet approaches the water there's a "ground effect" that causes the bullet to flatten its trajectory somewhat... they all touch the water slightly nose-up.... As always Gav's marksmanship is impeccable.... :-)
2:52 The amount of water displacement from something only a few millimeters in diameter and length... It kind of helps you visualize just how much kinetic energy is actually in a bullet, even one so small. That's crazy.
Coming back to your channel after years and seeing a bunch of content is a joy, and the metrics you include (bullet speed, slowing, etc) is always just perfect. Thank you Gavin and Dan for continually making content to all our hearts' desire
After seeing the disturbance of the water, I’d love to see footage of different rounds being fired just above the surface of the water. It would be interesting to see differences between various velocities, calibers, and bullet shapes. Thanks for the awesome videos guys!
Despite seeing bullets bounce off water in other videos, you two still manage to create fascinating footage of things we wouldn't quite expect to happen. Top notch!
@@FishFind3000Dan was an ammo/explosives expert in the British army. He knows what he’s doing and we probably saw every single shot he took for this video
You guys have always been a bright spot on the RU-vid landscape. Your content is, without a doubt, some of the most interesting to be found on this platform, but also it’s the enthusiastic and entertaining banter between you two that sets your channel apart from so many others. Thanks for another great video.
Yeah they're incredibly lucky to have each other. Best friends make the best videos! Makes me wanna watch some more Good Mythical Morning. And maybe even rerererererererererererewatch Good Will Hunting...
this might actually be your best video yet, the imagery, the speed, the unexpected physics... I would have watched this video for 45 minutes if you uploaded more content! Just perfect.
I was genuinely surprised that they ended it. So many questions that they raised that could have been answered. Also, why didn’t we see any tanks get exploded? You framed it up multiple times. Hopefully the destruction is in another video.
I think the bullets were deformed from initial impact with water, not from bouncing off of the glass. Bad assumption on their part, tho' understandable. :)
You can always trust the slow mo guys to do something, that to normal people looks impossible, on their first try and keep consistently doing it. Incredible lads
The Slow Mo guys are no doubt one of the greatest youtube channels in the entire history of RU-vid. They definitely deserve a spot on the Mt Rushmore of RU-vid.
This is a really good demo of why impact craters are always circular. Despite the low glancing angle, note how the bulk of the water is displaced more or less spherically. Strange things happen when something hits something else very fast!
This is what i was wondering about in this video! You could see the water that was displaced by the bullet moving through it was a thin small line splashing up the sides and doesn't really affect the water under the surface much. It's the same type of water displacement you'd expect from a speeding boat with a very pointy bow. But then you see after it leaves there's this invisible impact force blasting a sphere into the depths of the water and I'm sitting thinking "where did that energy come from?!" With normal water displacement you expect that the water pushed aside from the bullet will com crashing back into itself to fill the gap, and that would generate an upward splashing effect, like the kind you see when you drop a large rock into water. We also know the bullet hit with a lot of speed, and the faster the speed of the object, the higher the impact force it makes. With the amount of energy absorption we see from the water (the mentioned 30% speed loss in the video) I expected to see some sort of impact force in front of the bullets trajectory. as the water recoiled from absorbing that energy. But instead we see this perfectly circular blast that originated from the back of the trail, and it happens well after the bullet has already left the water?! I have so many questions! Why is the impact perfectly spherical? Why does it form at the entry point? Why does it take so long for it to happen? WHY?! This is so weird and interesting!
Years ago my kids enjoyed these 2 friends enormously! As did I. Seeing them older today, their voices are different for sure, but the quality remains top notch.
This is such a special video. You guys are freakishly good at this. Also a fantastic use of auto focus throughout the piece. Dan's reaction at 9:32 is my favorite moment from this channel. He cannot believe the tank is in one piece; he has to see it with his own eyes.
There was a moment in the slowmo of the first shot, where the splash above the water and the displacement in the water formed a near perfect sphere. That was absolutely amazing to see.
@@5peciesunkn0wn that really did happen in WW2 when the British Navy was trying to sink the Bismarck the British Battleships were firing their main guns at point blank range
I think the glass didn't break mainly because the water in the tank actually held it together. I noticed a small moment of cavitation between the water and glass which should be a temporary vacuum created by the glass moving faster than the water could flow. This would mean atmospheric pressure on the outside of the glass and vacuum on the inside creating a "split-second Rupert's drop" scenario. I would love to see a video exploring how much impact it would take to overcome this
I was about to comment this, it's also what I've thought, the water strengthens the glass because the glass can't expand due to the vacuum it created. The glass is pulling the water but it can't because of the weight and surface area of the water.
Also Aquarium glass is held together with silicone, which holds some elasticity and gives the glass some leeway to absorb an impact without breaking, I would assume. You can clearly see the glass bending a bit and also being pushed back, while the silicone stretches out on the sides and some miniscule amount of water escapes.
Yes I think so. The water is stationary and will require a plenty of force to get moving while it shares a common surface with the glass. So much force that indeed there is visible cavitation on the affected surface where the glass tries to rip itself away from the water.
Comment But also, thank you so much Gavin and Dan. The math and work that is done in the background to get a seamless little tidbit of knowledge, like the 30% decrease in speed… incredible
That first 9mm tank shot is just *chef's kiss*. I bet the presence of the water next to the glass absorbed the shock wave, within the glass surface, enough to prevent it from shattering.
I wonder how many times a day these guys will be walking in a store, see literally anything and think: “Ok but, what if we shot it with a gun?” Fr tho, love all the videos lately!
When I was in the Marine Corps I was stationed with the 31st Marine Expeditionary Unit we were out in the Pacific and did a night shoot with 50s and watching the rounds Ricochet off the ocean into the sky was amazing
Seen that while I was in the navy was well, it's quite a sight. 5 inch shells also ricochete, but at best you only see the splashes, it's a bit fun trying to guess where the next splash will be and how many splashes, saw one shell bounce 8 times
You both have kept me company for a long time. I was such an early subscriber and I feel like I’ve grown up along side you. Saved my life with your videos a few times. Always worth saying that. Please know you guys are heroes.
I am now very interested in seeing how a supersonic round at full spin travels through water. Not sure how the local high school swim team would feel about sending a .308 round into their pool but the comparison of those actual results with the myriad of Hollywood movie scenes (with bullets traveling through water) would be fascinating.
Mythbusters did this. Essentially anything really fast, like super sonic rounds, just disintegrate when they hit the water. The slower bullets are the ones that actually travel through.
What I love about the bullet bounce is that you can see a tiny amount of water coming out of the joins as the glass is flexed enough to create a gap for a fraction of a second.
I think that water was already outside of the tank from splashes by the previous shots. Because I find it hard to believe that the seal fails and then reseals itself.
@@cinemaker321 That's certainly a possibility as well. I suppose it depends on how the seal worked in the first place, if it was something like Silicone at the join it might have held the seal, or be leaking so little that it didn't really matter once the glass flexed back.
I feel like Dan is secretly a crime fighting superhero at night, and his enthusiasm for getting a great slow mo video makes him forget to hide his superhero skills from us mere mortals!
For me Gav and dan give me the fix i used to get when i watched Mythbusters, From a fellow brit thank you for all the content and making me smile, laugh and learn something all at the same time. Also watched gav gaming for years 😃
Definitely one of my favourite videos from you guys! Completely subverted my expectations. It was fascinating how there was like an entire layer of cavitation over the end panel of glass when the 9mm hit it.
