Explosives Expert Rates Unrealistic Movie Explosions


Rodger: My name’s Rodger Cornell. I’m an explosives engineer. Will Ferrell: Oh my god,
how do they walk away in movies without flinching
when it explodes behind them? There’s no way! Rodger: Okay so as soon
as this clip starts there are a couple of
really pressing issues that you should be focusing on. The first is if you have grenades and other weapons, you
shouldn’t be carrying them around inside a guitar case. On top of that, as soon as
he pulls the grenades out you’ll notice that he pulls out not one but two of those pins with his teeth. I’ve tried it a few
times, and you really have to put all of your strength
to get that thing dislodged. So pulling any kind of grenade
pin out with your mouth unless it’s been tampered with beforehand is just completely unrealistic. Antonio Banderas: Jesus Christ. Rodger: The most common
misconceptions I’m aware of. One is that any explosive device when it goes off will throw a human being into the air. The detonation itself and the pressure wave,
they’re gonna do plenty of damage to the human body. Propelling you into the air isn’t gonna be one of the things that you experience. So being thrown is not really a thing. You also see that just
from those two grenades, you have this gigantic fireball. Grenades, especially a
military grenade, is gonna be composed of what’s
called secondary explosives and these secondary explosives go through detonation processes. A detonation process is extremely rapid and it’s certainly not gonna be this prolonged explosion
that you see here. When you see a gigantic fireball and you see just flames everywhere and you can usually assume that they’re exaggerating quite a bit. I mean it’s not that surprising. It’s a Quentin Tarantino movie, so I really wouldn’t expect anything less. The only explosive device that you see in that clip is what seems
to be one pack of dynamite. Dynamite’s used specifically
for blasting operations so even though it’s made
for situations like this if you have just one bundle in the corner of a house, you will never
get any kind of an explosion on this order, you might have
a chunk of the house missing right where that explosive charge was but that’s about it,
the house would probably still be standing, unless there were a lot of other charges placed about the house that we’re unaware of. Certainly not every piece of the building would be in flames. Samuel Jackson: Son of a– It looks like he’s in a dummy town. Once he hears sirens, he realizes that he’s about to be in the
middle of a nuclear test. Harrison Ford: That can’t be good. Rodger: The refrigerator’s lead lined and the reason this is important is that the lead can actually
block certain types of radiation. So that’s the premise is that all the lead
in this fridge is gonna block the radiation and
somehow protect Indiana Jones. Some of the things that are
depicting are somewhat accurate. I mean, a nuclear detonation
or a nuclear event would produce all kinds of light. And it’s amazingly destructive. So they’re showing the
force of it correctly just not how it’s gonna impact the fridge which is the main issue with the scene. Sure, the lead lining is
gonna protect a little bit from some of the radiation,
although it’s not nearly enough to prevent all of the radiation from affecting you, there’s
no way you can survive an impact like that. The fact that he gets out immediately and he’ll actually walk up to look at the aftermath of the mushroom cloud from the nuclear event, there’s
a ton of nuclear fallout when you have these events, and you want to be as far away from this as possible because the radiation that it produces it sticks around for quite a while. And the fact that he lives on in the movie and doesn’t die in a couple hours from radiation sickness is
just completely ridiculous. Right off the bat it’s Michael Bay, it’s
a Transformers movie you have Deceptacons running around. So how real can you expect it to be? When you see the fighter jets in action you’ll notice these bursts of
light coming off the bottom. If I had to guess what that was, that would probably be flares. And a lot of times
they’re used so the planes can avoid heat seeking missiles. They’re a source of heat
that can distract the missile from continuing to fly towards the jet. Now whether or not the Deceptacons use heat-seeking missiles I have no idea. Traffic Controller: Q1 snipe 090. You are approved to drop
your 2000-class JDAMs. Rodger: So during this initial explosion, what I’m assuming they’re
doing is essentially marking their target. If you’re gonna drop ammunition that don’t have any kind of propulsion or guidance, you want
to be very, very sure where you’re gonna drop those bombs. You see Shia LaBeouf get
just almost catapulted into the air, it almost
actually looks like he’s stepping on like a trampoline. I can’t see any reason why he would be tumbling in the air like that. The pressure wave that’s radiating is moving outward, away from the explosion so if you were to be thrown at all you might be thrown backwards
and fall to the ground but setting that all aside, there’s at least realistic situations. Some of the things that the aircraft did that progression from marking your target and then dropping the
energetic load on top of it my guess is that he was probably consulted as to how the Department
of Defense would actually go through their procedures. He takes essentially his claws and he strikes them against the rocks to create a spark to initiate the flame. If I’m remembering
correctly, it’s Adamantium what his claws are made of,
which is completely fictitious. I have no ideas what the properties of that material would be, but
there are a lot of metals out there that don’t spark. There are other ways to initiate fuel. That seems like a pretty silly one that probably wouldn’t work out. That’s a very rocky surface. Even if you got it to start burning it would probably die out before it ever reached the helicopter. I would never expect this to explode. You have a helicopter that’s crashed and that’s already leaking fuel. So when the fuel tank ruptures there’s no pressure
vessel that can heat up that can allow pressure to build where you’d actually get
some sort of an explosion. But if you had an explosion on that scale you’d have pieces of that
helicopter being thrown in every direction, not to
mention the pressure wave that’s produced, so he would definitely hit the ground at some point. He regenerates, so I guess
you could walk away from this. He’d be fine. You see some grenade
being launched at Hancock. And he somehow deflects it into a car. If we just accept the
fact that he can’t be hurt and that he can just deflect bullets and that’s fine, there’s
still really big issues with this scene. The effect of the grenade is unrealistic, the way
it initiates is incorrect using the police car as a way of stopping bullets is just ill advised. Cars don’t stop bullets. Cars can deflect bullets. Cars have a lot of weak points, so you wouldn’t want to
ever use it as a shield. I would expect the doors to
have bullet-proof inserts but that’s about it. The roof of the car and
the floor of the car are probably pretty thin, those are gonna be the most vulnerable
parts of that vehicle. The way he’s holding it is
probably the least safe way that he could be using
that car for protection. Will Smith: Good job! To create an explosion that massive you would need more explosive material than you could carry with you and you would need to plant it everywhere. It would take just unlimited
financial resources a huge amount of time to place the charges where you need to put them. They try to add in some
cool sound effects. It’s not gonna sound anything like that. The actual audio event is very rapid very loud, and it’s more of a crack. They try to show the shock
actually moving outward essentially past Denzel,
you can see the grass start to move forward,
and then retract back. There, you see that little. That was a shock wave moving past, so seeing that sort of
motion within the grass in that scene could actually be realistic. If you’re that close where
you can see the shock around you, it’s gonna at least hurt because you have this
sudden change in pressure. It’s gonna feel like
someone’s at the very least just punching you as hard as they can. You’re not just gonna keep walking. All sorts of metal being thrown. There’s fragmentation everywhere. This is one of my favorite movies so I really hate laying into it like I’m about to. So he essentially rigged this hospital with explosives, he’s
setting them off wirelessly and then he’s just watching
as the demolition unfolds. You could have explosions
going off at different times and different locations so that’s actually not unreasonable. What is unreasonable is
to pull that off would be expensive, and you’d
also need to somehow go through a hospital and
place all these charges without anybody noticing,
I’m not entirely sure that he would have the resources the time, and be able
to disguise everything to actually pull something like this off. Especially given what the Joker’s wearing. Heath Ledger: Hi. There’s no way he would go
through this entire process without being seen by somebody. Jonah Hill: It’s gonna explode! Channing Tatum: Oh my
god, roll up the windows! Jonah: What the f*** is that?
Channing: Roll it up! Channing: I don’t care just do it! – The funny thing is, this scene is one of the most realistic scenes
we’re probably gonna see. There is one resounding
issue with this scene though. All those pressurized tanks, the fact that all these things are ruptured and just sitting there. Jonah: What happened? Channing: I don’t know.
It just didn’t explode. Jonah: That’s weird. That would never happen. Jonah: I really thought
that one was gonna explode. This I think is actually
the most accurate scene so you have a fuel tank
that was just riddled with bullet holes, so it has no way of accelerating the reaction. Channing: That’s what exploded? I don’t know why chickens would explode. Their fecal matter could probably combust the wooden cages could light on fire but why you’d get an
explosion, I have no idea. I think the scene’s kind of intending to be a bit ridiculous,
and it definitely is. Will: What accounting firm is
closed at 11 AM on a Tuesday? Mark Wahlberg: Oh this is a s***hole. The flame’s unrealistic, but
the way they’re pushed back is actually somewhat believable. So the fact that they aren’t cut up and that they’re not bleeding profusely. The fragmentation in that situation would be much more deadly. Will: I can’t hear! I can’t hear! The way he’s complaining is unrealistic but the fact that he’s complaining about his ears is actually realistic. When you have blast over pressure there are certain parts of the human body that are susceptible, are very susceptible to shifts in pressure. Your ear drums are one,
and your lungs are another. In extreme cases, if the
pressure was strong enough you could rupture your
lungs, and if that happens or if anything near that happens he’s not gonna be talking. He’s just gonna be laying there gasping for whatever breath he can pull in so he seems to be in much better shape than I would imagine him to be. If you got hit with a pressure wave you’d probably be concussed as well. Will: I need an MRI! So an MRI might not be a bad idea.

  1. Well, the US Army did some test where personal would walk toward a nuke after it has detonated
    They didn't die within the next few hours

    Though they may have an increased risk of Cancer today if they're not dead yet

  2. I don't understand his analysis of The Dark Knight at all, he just questions whether the Joker would have the available funds and if he'd be able to place the charges without being noticed…. for one there's all kinds of ways to explain away both of those issues, and for two he said absolutely nothing about the realism of the explosion itself… which is what I thought the whole point of the was.

  3. Kinda upset this guy doesn't have a tattered cowboy hat, white beard, a lazy eye, a missing front tooth, bushy eyebrows, and overalls on….

  4. I'm really surprised that he doesn't mention gasoline. He's an "expert" but he can't identify obvious gasoline explosions??? Near all of these are gas fire/explosions.

  5. C'mon Avatar Hometree. Also just because a fuel tanker has a few bullet holes doesn't mean it can't build up pressure. If the fuel was ignited, the acceleration and build up of pressure would be much faster than could be released by those tiny holes. If the manhole was fully open I still wouldn't want to be too close.

  6. with regards the wolverine helicopter scene, the heli in the scene is a turbine powered aircraft. that means Jet A1 fuel, i saw a tv documentery once about fuels, doesn't jet a1 react like deisel. i mean you can throw a lit match into a cup of the stuff and it'll just put the flame out. it needs to be in a pressurised vapour form to burn. I could be wrong.

  7. Next video: regular guy with common sense will tell stupid realists that movies are meant to be unrealistic and fictional.

  8. Michael Bay actaully worked with the military in ALL the Transformers movies he directed. They are real soldiers doing they thang.

  9. When they exploded atomic bomb's in the Nevada desert the military had soldiers march into the drop zone. So the part where Indiana Jones looks over the ridge is accurate and this guy is wrong. Look up the video on YouTube and you will see soldiers marching into the Nevada drop zone of an atomic bomb with the mushroom cloud in the air.

  10. I thought he was actually going to rate the EXPLOSIVES not critique the realism of the movies lol, waste of 13 minutes, I was expecting him rate the live effects vs the CGI tells us what types of explosives would produce what effect vs what explosives are shown to produce, pointless

  11. Just came back here to say how dumb this stupid dude is. Contradicting himself the whole video, is so pathetic.

  12. I know they focused on the lead lining but I think Indy was just using the bulk of the fridge to minimise the physical shock of the explosion

  13. Last Action Hero – there are some explosions made ridiculous on purpose. Car explodes mid-air… to basically tell you the chase ended.

  14. Hancock is the very definition of a real life superhero I'm serious you seen how people are imagine if we had powers

  15. Cool video but this dude seems like he witnessed a test dummy(human) got blew back by a real controlled explosion

  16. The Joker part… Joker has henchmen everywhere, it is likely he had people planting the explosives in the hospital before causing them to be evacuated.

  17. Actually you can stand in front of a nuke like Indiana Jones did and not die for a long time. All those soldiers survived with long lives at the real tests and Nagasaki survivors as well. It turn out that explosive experts aren’t physicists.

  18. Yes we understand that's what really movies are about I don't see the reason of this video except for you are trying to discredit some movies

  19. Okay, but I would like a one on one session with Rodger to test… some explosives. This is a very interesting topic.

  20. I think the Joker, especially this Joker in the Dark Knight who was able to acquire a pile, NO, a heep of money that looked about 10-15ft tall, could get a hold of very expensive explosives and stuff.

  21. So can a plane that crashes into a building bring the building down in its place and not affect surrounding buildings like lets say in New York?

  22. Dammn, all these thirsty comments about the explosives engineer smh
    But on the other hand, he can literally explode his inside me lol

  23. He didn't rate the explosion in the Dark Knight, he just said that the Joker never could have pulled that off. Stick to your status quo dude.

  24. You know joker have shit ton of money (like a huge mountain of cash which he burns )and he do have alot of armworkers they could just place the bomb and kill the person who noticed them.

  25. To be fair, Michael Bay used actual explosions when filming, so you can’t really judge the physics of his explosions too much.

  26. I hate to get into it this much but the joker doesn’t do everything himself, he has hundreds of people under his thumb most of them cops, I can totally see how all of the charges we placed around the hospital I’m betting that most were on the outside and some on the inside

  27. In regards to cars being used as cover. If you have no form of bulletproof lining in your doors, your best bet is where the engine is. It’ll stop smaller calibers which is ideal in a domestic setting.

  28. How did you guys not do Shooter (movie)? The scene at the house w the napalm,pipe bombs, etc. and the end scene with the propane leak. That would have been perfect. Save it for rd 2!

  29. For someone who loves Batman and Joker he seems like he doesnt know anything about joker, he stole from the mob, he planned everything god knows how long before he finally got to executing his plan, Joker is THE planner so…
