Wow if you slow it down you can see the paint get burned off, then the metal turns black as if it's already burned right before the wave hits. That's hot!!!
holy shit. i always thought the car was just dusty that smoke before the blast wave is the paint instantly vaporizing off the car from the intense heat
There are clips from Operation Plumbbob showing pigs in cages being hit by the thermal pulse. They all survived but with extensive burns to uncovered skin. The same thing would happen to human skin, at least third degree burns if you were close enough to the fireball.
Note the film frame rate for these clips is 64/sec., a bit over 2 1/2 times the standard Hollywood film frame rate of 24/sec. Standard slow motion is shot at 60 fps.
Jason Robards was at least this close in the movie The Day After but somehow got much less burns, plot armor. Steven Guttenberg also had plot armor too.
After the initial blast that knocks the vehicles back, there’s a moment when they reverse direction like they’re being sucked back toward the blast origin. What are the physics behind that occurrence?
There are two phases to the blast wave, a positive (outward), and a less powerful negative (inward), air rushing back in to fill the vacuum created by the blast. In this case, because of the low height of the explosion (about 520 feet), there were also two outward waves, a leading precursor wave and an incident wave that bounces off the ground and shortly catches up to the precursor, the two joining together, resulting in a stronger positive wave. It's all explained in the Wikipedia article on Grable.
After the Shockwave it sent out, everything the Shockwave reached turns into this vacuum zone, then, it's all sucked back in because air hates being compressed, and bc the heat crates a vortex
Yeah. If you look where the main air streams go the fallout from the Nevada test sites blankets the Midwest. They happen to have some of the highest cancer rates in the US, but wtf do I know.
@@l8tbraker But one would have to assume that the film is running at normal speed to make that calculation. The way the vehicles are flipping over makes me think that it’s slowed down a bit. Run the film at 2x speed and it looks more natural to my eye.
There are several color films of the fireball and mushroom cloud for *Grable*, which was the proof test of the 280 mm atomic cannon and projectile. First detonation of a uranium gun type device since Hiroshima.
Do you the films of when they tested on living animals, not sure if the viewing group would want to see that. I did many years ago and it is not for the faint of heart.
I still think some of those are bottles along with some of the houses and trees and some of the test they just don't look right. remember question everything,
Notice how the paint on the vehicles is burnt off, before percussion blast... imagine if they figured out how to burn the vehicles' paint without the blasts' percussion... Now relate that same action to the burning of vehicles in recent fires in tecent years in 2023.
Imagine your skin burning in the heat, the last thing you hear is your ears sizzling from the heat and then the blast wave punches you into the Grim Reapers boney hands.
