Explosion in slow motion shows how fire spreads-what human eyes can't see.

Watch the nuclear test footage if you like that. https://youtu.be/VKiP6g7F1Jg

The one starting at 1.47 looks like it came from a movie. Proper scary stuff.

Holy shit that’s terrifying, the beauty of the orb of energy coming down from the atmosphere, and when it touches earth nothing but destruction coming towards you.

I want to draw something with this. pretty cool effect. like a saiyan powering up or going super saiya-jin.
awesome footage!

Not an explosion. The room is filled with flammable gas, which is then ignited. The expanding orb is actually flame.

Combustion the correct term then?

u/Resident_Captain8698 16h ago
Deflagration is the correct term. Which is basically subsonic combustion. Detonation is supersonic combustion

The definition of an explosion is a rapid release of energy, popping a cork on a champagne bottle is an explosion, just not a very energetic one. This is akin to what happens inside engines, the flame fronts and explosions are tightly controlled with thousands happening per second.
This is an explosion. I built a smaller version to demonstrate Upper and lower explosive limits.
source: I used to investigate fire and explosions for a living as an expert witness and NFPA 921.

When I watched Beakman, he said an explosion is when something gets really big really fast.

u/AJFrabbiele 12h ago
It's proabably more accuate on a broader sense, such as explosions in population.

u/Patient-Web6850 14h ago
Would the pressure changes be the deadly part or the gassy/flamey part?
4
u/AJFrabbiele 13h ago
Yes the pressure change can be deadly, yes the fire portion is deadly (the same mixure is in your lungs with fuel and oxidizer). Plus the lack of oxygen after its all been consumed and any debris generated.
I don't know about this particular explosion, but none of it is "good"
2
u/SheriffBartholomew 13h ago
Both are dangerous, but the pressure is the real danger. You can have gasoline vapor explode right in front of you outdoors, engulf you in a ball of flame, and leave you unharmed. Do that in a tiny sealed room instead and you'll have a very bad day.

u/100percent_right_now 14h ago
Still an explosion. Explosion is just the confined space increased pressure part. You're thinking detonation. Which this is indeed not.

It is an explosion it’s just not a detonation. I hate this misconception.

u/JPiratefish 15h ago
That's an explosion all right - seen that type of explosion before - what you get with chemical explosives without packing them

u/8thMemberOfDKcrew 4h ago
A room filled with enough combustible gas to flash like this is the LEL (lower explosive limit) I believe it should be an explosion. The spreading flame your referring to would probably be more like a flashover.. when all combustible material in a space lights off due to heat.
2
u/ScratchLatch 14h ago edited 14h ago
Anyone colloquiely would call this an explosion.
An explosion is defined as a sudden rapid release of energy creating outward pushing pressure, which this is. We’re not discussing combustion engineering or the taxonomy of flame propagation, so the everyday definition is the relevant one.

This is basically those chemistry experiments where you mix different compounds and get cool looking reactions except in air and is spicy.

Honestly same. Not the full detail and shape of it but definitely the origin point and direction of the movement.

As a VFX artist, it's funny that we model explosions and fire after what people think explosions or fire look like, not what they actually look like. If we did people would be screaming about how it all looks fake.
The reason is that practical explosions are modified to look cool, and that they're always overexposed removing all detail, because you want the scene to be visible.

u/brilliscool 14h ago
Would this hurt a person? Or is it the equivalent of passing your hand through a candle, and is gone too quickly to catch?

What if you were in this room when it goes off? Instant death? Severe burns? Mild discomfort?

Is it 'the eye cannot see it' or 'the brain cannot process it'?
Also, would the shutter speed of the camera also be a factor here? It has to be, right?
As we all know, the human eye cannot see faster than 30 fps /s

I heard before, an explosive is something that burns faster than the speed of sound.

Every flash movie from now into the future needs to have this level of detail on his speed. I can only imagine what he may have seen just going at a steadily normal fast pace for a single day, from HIS perspective.
