Island Copper Port Hardy B.C. 1982. Third largest open pit copper mine. A drop cut blast on the 680 bench. If it was not raining in Port Hardy, it was about to. When we did a drop cut or sand blasted boulders in the bottom of the mine we saw these compression waves coming out of the mine. We did not have high speed photography but the shock wave created an expanding bubble of water vapour that was very easy to see.
rAdiant Jet Yes, they do. Others called it shellshock. They are being researched on any type explosion no matter how small or large it can get and how it effect your body. Even in foxholes, you still get effected by it. National Geographic have a story on it few years ago with a cover of a marine holding a mask.
I think it was. Gunpowder does not really go boom big until it is sealed and under pressure. Even a barrel would be better. Ammonium Nitrate and diesel is different. I think you are right Sean.
Most of the rest of the world doesn't have pickup trucks and think they are pretty useless and stupid vehicles, so he was making a sort of off-hand joke there about mericans and their love for pickup trucks.
You want the song? From his website: UPDATE JAN 3rd 2011: Plans are (finally) afoot to release the soundtrack to Richard Hammond’s Invisible Worlds. It is a few weeks away yet, but if you want to be notified when it is available, please do let me know and I will drop you an email when it is released. I want this track so bad! Can't wait.
If you want to see great footage of shockwave propagation, check out the Pepcon explosion & the camera is so far away that you can see the shockwave fly across the landscape.
“In the thin air, the shock wave can cause immense destruction, explosion not required”. Put alternately, with difficult but not impossible physics in like electrostatics and plasma speakers one could generate the destructive power with purely electric (no combustion/explosion/toxins)
@lionsforlyons nope its not anfo he said 300 meters per second (low explosive) thats way 2 slow for any primary or high explosive. anofs vod is around 3300-5000 mps depending on confinement and booster
I noticed that too. Distance 1 mile (5280 feet), speed of sound 761 mph at sea level. Time for a shock wave to arrive is T = D / S = ~7 seconds for 1/2 mile = ~3 seconds. Faking physics just makes people dumb and makes the show look dumb too.
That is true. But even for people who don't understand physics it should be obvious. One can literally see the sound wave approaching on the high speed footage.
I'm not going to assume they didn't mic the immediate site. Incidentally, a shock wave is not a normal sound compression wave. It can travel at twice the velocity of sound.
Correct Eric. In fact, a shockwave can be so thin and fast-moving that we cannot hear it (much), although it still has after-effects on our ears. I've had the experience of setting off tiny amounts of PETN using a hammer on a steel plate and I couldn't tell the difference in sound between just the hammer hitting the steel without PETN and with PETN - however I could tell the difference because my ears would ring after one but not the other. (Also the PETN would just disappear instantly and there would be tiny bits of steel missing from the surface of the plate)
@AneierHSNO4 Yes, but he was commenting on the speed of the shock, which though initially travels with the gas/fireball wavefront, will rapidly slow down to the speed of sound (~330m/s).
What was the flash of white which moves rapidly upwards some several microseconds into the burn? It's best seem at about 3:58. Is this the burn reflecting off of the ground but delayed by rapidly diminishing overpressure? He doesn't mention it in the video and the morphology of the burn all makes sense except that flash of white moving upwards so late in the process.
black powder is an explosive, but when they poured that, it definitely looked like a binary. the explosion itself throws a lot of dark smoke indicating an accelerated oxygenation. black powder and flash powder generally throw white, but wasn't there, don't know. They say "gun powder" and that includes black, smokeless, nitrocellulose, and a whole class of propellants, so there's a lot of latitude here. cool vid, though.
This blast had to be kept secret otherwise thousands of guys would have dropped everything and raced to get there and would be surrounding the blast site.
How close do you need be from the shockwave to be killed? and what happens if the shockwave crashes against you in a close distance?? like would it be the same as you being hit by a truck or a recking ball?? Will it just smash your organs to meat paste?
That was anfo ,and what a crock .They dont need an armoured car .Ive been around blasting for ,30 ,years .They used prima cord and a pistol cap to detonate. You can just as easily use a fuse and cap. Which will give you plenty of time to walk and easily drive ,away.
Why do they fudge the audio to make the sound of the explosion the same moment as it is seen from far away? I mean, when you watch a baseball game, you see the ball hit before you hear the crack of the bat, right? This suspends reality for the whole video. So sound travels faster than the shockwave?
And how much Wildlife was killed in the making of this film for something we already know and have plenty of footage? (Don't forget to include the flora, that's part of the wildlife too. Plus all of the plants and animals that were damaged, maybe not killed, but will probably not be able to reproduce probably dying soon afterward, causing ripple effect in population loss in both flora and fauna abound for years to come). Gosh, BBC, you could've asked the U.S. for some footage. Dont'cha know we're the #1 fanatics for blowing things up?

what perfect about this video is the music playing while showing the explosion
it's amazing what these super slow motion cameras can capture great video
Gerry Maloney I want one to take a video of my explosive diarrhea.

Brought tears to my eyes, absolutely beautiful :,)
so deadly and yet so beautiful.
wow the shockwave can be seen seen soooo clearly in this
No one does it better than the BBC.
So beautiful!
Damn... I have a flu and I am tripping with the music.
Nice video. Thank you Trumps up!
Amazingly beautiful..
Goddamn that is poetry in motion. Nothing says love like crushing your enemies bones with high-explosives...
The vast, vast majority of injuries from explosives munitions are from the shrapnel or burns. The shockwave itself rolls off very quickly.
thats beautiful
The shock-wave took on the shape of a liberty cap mushroom!
Alright, that was pretty cool
It's pretty cool! But those shock waves will turn your organs to mush!
rAdiant Jet Yes, they do. Others called it shellshock. They are being researched on any type explosion no matter how small or large it can get and how it effect your body. Even in foxholes, you still get effected by it. National Geographic have a story on it few years ago with a cover of a marine holding a mask.
a shockwave rifle would be awesome ... like the alien weapon in District 9
Fire any rifle and a shockwave exits the barrel, just ahead of the bullet itself.
Destroy all humans!!!
That wasn't gunpowder
Yes it wasn't.
Chris Diehl
No it wuz!
It looked like ANFO to me.
+Sean Breheny
+Atouk
You would have to pack gunpowder to get that type of reaction.
Yes, it does look like ANFO.
I think it was. Gunpowder does not really go boom big until it is sealed and under pressure. Even a barrel would be better. Ammonium Nitrate and diesel is different. I think you are right Sean.
they are half a mile away from the bomb site. that means the wire stretches a half a mile long. thats a long wire
Kong Chang it's not wire, that's detcord, it's an actual explosive on its own, it's used to set off larger explosives.
Wow! skeletor and John are super smart!! loooosers
Kong Chang Look at the big brain on Kong.
Kong Chang the internet fiber optic wires in the bottom of the ocean puts that hot wire to shame
Kong Chang look up ocean cables, they literally cross the ocean. I never heard of it until a year ago.
thanks for the vid ;)
It's beautiful.
0:28"Everyone must be 1 mile away, that's why they're running away in pickup trucks"🤣
Takes too long to walk a mile. ;0)
Most of the rest of the world doesn't have pickup trucks and think they are pretty useless and stupid vehicles, so he was making a sort of off-hand joke there about mericans and their love for pickup trucks.
Also captured in the high speed is the negative pressure phase of the detonation.
its beautiful...

I want this track so bad! Can't wait.
nice, you guys should have put some objects out side of the explosion nust to see the shick wave damage
Beautiful
I used music recognizer but there was no results. Friends didn't know too :( Hmm, I will try with web
If you want to see great footage of shockwave propagation, check out the Pepcon explosion & the camera is so far away that you can see the shockwave fly across the landscape.
“In the thin air, the shock wave can cause immense destruction, explosion not required”. Put alternately, with difficult but not impossible physics in like electrostatics and plasma speakers one could generate the destructive power with purely electric (no combustion/explosion/toxins)
It's like that expanding transparent air like a dome
But thanks for the intentions :)
I'll ask my friends, maybe they'll know :) And then I'll write the title here, ok? :)
that looked scary , and the music sounded even scaryer.
LOOK its the TIV2 everyone!
@1:28 not one fuck was given. none. at. all.
...saw that, too. no blinks... no fucks...
Thanks for the 240p
Very cool.
This would be amazing in HD...
without a doubt the most beautiful physical phenominon
@lionsforlyons nope its not anfo he said 300 meters per second (low explosive) thats way 2 slow for any primary or high explosive. anofs vod is around 3300-5000 mps depending on confinement and booster
yeah..... gunpowder....
"... thousands of pounds of gunpowder ..."
Actually,. it looked more like ANFO to me. Much cheaper.
This explosion was an inside job!
Why add in the fake explosion sounds? It is such poor production quality when physics is ignored.
I noticed that too. Distance 1 mile (5280 feet), speed of sound 761 mph at sea level. Time for a shock wave to arrive is T = D / S = ~7 seconds for 1/2 mile = ~3 seconds. Faking physics just makes people dumb and makes the show look dumb too.

(Also the PETN would just disappear instantly and there would be tiny bits of steel missing from the surface of the plate)
Shhiiitt... I just learned more about physics than I did this whole year in this comment section.
@AneierHSNO4 Yes, but he was commenting on the speed of the shock, which though initially travels with the gas/fireball wavefront, will rapidly slow down to the speed of sound (~330m/s).
The men inside the armored vehicle, would they have suffered any internal damage? Even slight?
@MidnightRedemption Yeah because the air at the wavefront is much denser, so light travels through it more slowly.
@kajkatrixi I have no idea,sorry .I have searched on his website but I haven't found the name of the song.
What was the flash of white which moves rapidly upwards some several microseconds into the burn? It's best seem at about 3:58. Is this the burn reflecting off of the ground but delayed by rapidly diminishing overpressure? He doesn't mention it in the video and the morphology of the burn all makes sense except that flash of white moving upwards so late in the process.
Sorry, it's because of youtube. They blocked the video in some countries, because it has content that is owned or licensed by BBC Worldwide :|
@kajkatrixi it's David Schweitzer
1:20 is where it starts.
You can see it at full speed.
impressive
Bullshit. That's not gunpowder, they're high explosives.
black powder is an explosive, but when they poured that, it definitely looked like a binary. the explosion itself throws a lot of dark smoke indicating an accelerated oxygenation. black powder and flash powder generally throw white, but wasn't there, don't know. They say "gun powder" and that includes black, smokeless, nitrocellulose, and a whole class of propellants, so there's a lot of latitude here. cool vid, though.
That was ammonium-nitrite. Used as an explosive, it is a 'high', 'Low Explosive'.
nitrate
Sparklers.
Fertilize corn corn and power a tractor
Looks Like EMRTC - Energetic Materials and Research Testing Center.
How does it bend light like that?
This blast had to be kept secret otherwise thousands of guys would have dropped everything and raced to get there and would be surrounding the blast site.
That is cool
Nice detonation and view, but I hate how they re-mix the audio to take out the delay.
I like the one part where there was a pixel that looked like a shockwave.
How close do you need be from the shockwave to be killed? and what happens if the shockwave crashes against you in a close distance?? like would it be the same as you being hit by a truck or a recking ball?? Will it just smash your organs to meat paste?
What song is playing in the background?
is that a lensflare at 2:27? up high.
Gotta love the angelic music accompanying the human-created device of mass destruction, as if this were something of beauty to be admired.
You can't deny that it's beautiful.
What about little animals and bugs, are they clear
... and yes, your comment was pending :)
@EXPLOSION 988 hi
I'm surprised party snaps were that explosive
Fernando De la Cruz lopez - Hahaha, it's ammonium nitrate ammonium powder - Binary Explosive
That was anfo ,and what a crock .They dont need an armoured car .Ive been around blasting for ,30 ,years .They used prima cord and a pistol cap to detonate. You can just as easily use a fuse and cap. Which will give you plenty of time to walk and easily drive ,away.
@zapper911 You can buy it on Amazon. Link in the description bar :)
@ela070885 can you please upload the soundtrack if you have it?
what's that song called?
Song please that starts at 2:13??
Why do they fudge the audio to make the sound of the explosion the same moment as it is seen from far away? I mean, when you watch a baseball game, you see the ball hit before you hear the crack of the bat, right? This suspends reality for the whole video. So sound travels faster than the shockwave?
Destruction is Beautiful.
Every little boys dream. To blow stuff up just to film the shockwave.
@zapper911 Weird :|. Thank you for the link
y'all ain't gonna believe this shit but I done did an explosion
Anon Ymous DID YOU FART REAL HARD AND LIGHT IT??
The music is sooo peardy.
well someone just made it onto the no fly list.
crazy
starts at 2:40
Should have called it Visco fuse while you were at it.
Shock wave first visible at 2:20
some people get to have all the fun jobs.
So is it possible to create a shockwave without the explosion?
somebody couldhave reloaded with thatpowder!
Does anyone know the name of the soundtrack?
Music : David Schweitzer. There is a link in the description with his work for the series, including the one in the video
@lionsforlyons doesn't most gunpowder give a black smoke?
If they did it in the desert you would be able to see the shock wave coming at you it looks scary coming towards you....
SHOCKWAVE!!! FUCK YES!!!!
That's not gunpowder. gunpowder deflagrates, it does not detonate.
Imagine that as defensive weapon.
@kajkatrixi ok, thank you very much :)
Nuclear weapons are more impressive. That is like taking a firecracker to a fireworks show.
Wow.
ammonium nitrate and fuel oil (diesel)
And it's : "David Schweitzer" or "David Schweizer" ?
And how much Wildlife was killed in the making of this film for something we already know and have plenty of footage? (Don't forget to include the flora, that's part of the wildlife too.

@trapezeable Sorry, I don't have it :(
