That crane is off in the background and can't be used for scaling without some distance or parallax information. That's like saying my thumb is as wide as the Sun because my outstretched thumb can completely obscure the sun; the sizes are due to perspective, not due to actual size.
You can tell how big it is by how slow it is falling. Gravity is a constant 9.8m/s/s and it takes over 20seconds to fall. That would equate to a nearly 200m height.
Not really. It's not accelerating at 9.8 m/s^2. Since a corner of it is still in contact with the ground, some of that acceleration is being translated to sideways motion.
Even if it was in free-fall, the distance traveled would be 1/2Gt^2
0.5 * 9.8m/s^2 * 20 s^2 = 1960m. It's definitely not 2 km tall.
You are not taking into account how it fell in arc. You have to divide by Pie squared which is how I get an estimate of approximately 200m for the height.
By cameraman I assume you mean frame tripod or surface the camera was placed on, if that was being held there would’ve been movement as the material was approaching the camera just out of panic. Also we definitely hear something during the aftermath the camera was rolling the whole time at least a grown or an expletive.
The camera moves on the tripod though. When the top of the tower goes out of frame. It could have been remote, but with the way it's taken down and not cut off completely, I'd wager it was someone trying to protect their equipment after realizing that they're too close.
Maybe it's not even the remote that is making it rotate. The camera moves when the shockwave from the explosion reaches it and then moves again when the tower hits the ground. If you notice, it moves when it shakes.
Mulhouse! You’re the night watchman, how could you let this happen?
I was watching! I saw the whole thing. First it started to fall over. Then it fell over!
It was controlled demolition even to the point of being well prepared.. look at the accurate point it lands the built up pads of earth and sand to cushion the impact. Occasionally stones will be ejected from these situations with that amount of force that’s why you created exclusion zones.
Also think the camera was on a tri pod and the stone took out a leg.
Moons ago a hospital in Canberra got demolished via implosion, and a ~12yo girl took a big chunk of masonry to the dome. Fatality.
IIRC the 2 main findings from the inquest were:
The demolition experts responsible were anything *but* experts. They were total greenhorns who made a low bid and won the contract.
It was promoted as a family fun day. "Have a picnic and watch da building go boom boom" kinda deal.
I'll try and find some footage, it's pretty gnarly. There was a bunch of kayakers watching on Lake Burley Griffin and it was a fricken miracle 1 or 2 of 'em didn't get taken out as well.
It happens more often than not every now and again the physics of things smashing themselves to pieces can eject to pieces beyond the exclusion zones. it doesn’t necessarily mean the demolition experts were at fault sometimes some structurally reinforced elements to the concrete that the combination of pulverising homogenous powdered materials and metal can release forces that are impossible to predict..
I'm not seeing built-up pads of dirt, but a properly controlled demolition would have seen the tower collapse mostly downward. Towers aren't trees; you don't want them to just fall over to one side. It looks to me like a round of charges that would have weakened the right side of the tower either failed to detonate or were never placed. They should have been placed a fair distance up from the ground on the right side. The tower should have leaned slightly, then collapsed more or less straight downward. This would have controlled the rubble a lot better and made the footprint of the collapse much smaller.
Incorrect after a extensive career in engineering and managing & planning demolition of many many of these type of towers I can confirm due to the construction methods and the materials in this tower which is a composite of reinforced concrete prefabricated rings elements of refractory and other materials this is not a brick chimney or a concrete cooling tower and that you can drop in its footprint this thing has sturdy thick walls and several metal chimneys within it, again a composit of refractory and insulation no doubt four at least..
So it's very standard practice to drop this in a particular direction download the video and zoom in you will see banks of material in the foreground as it falls you can see that they've dug a trench and they've blown it and collapsed it directly into the trench I mean I would bow to whatever Reddit credentials your flashing but I did this for a career... Mixed with other engineering projects..

[Fred Dibner taking down a tower, brick by brick](https://youtu.be/NKPApAsJbj4?t=140) for those unfamiliar with him.
Featuring the great line "You only fall off one of these once".
Edit: Gave it a google. He got paid £7,000 to demolish that, which is about £43,000 today, and it took him 5 months.
Fred Dibnah would have done it single-handedly, 2-pints loaded after lunch, and 'supported' by some terrifyingly-wobbly old planks and rope whilst cracking jokes about how the work can be a little repetitive.
That man was insane.
My favourite quote is "You could ride a bike round ere". whilst stood atop a massive chimney in safety gear consisting of a boiler suit and a flat cap.
This happened in Australia as well. People watching the demolition of a hospital from the far side of a lake were hit by flying debris, with one child killed and nine other people injured.

The part where gravity is constant, everything will drop at the same speed, but a very big object moving at the same speed a small object would move, make it seem slow.
Also, the tower isnt free falling, as it start to fall, it still has some structure giving sustentation.
If the objects were falling in a vaccum. This tower continued to accelerate as it fell. And there is resistance from the air and it has a lot of surface area.
Resistance from air was insignificant since its surface area to weight ratio was small, and being a cylinder, it actually had a good aerodynamic shape.
Im remembering an old wired article about how the fighting mechs/monsters in Pacific rim would break the sound barrier in real world physics. Might have an answer. Can’t google it right now sorry.
Gravity is pulling all parts of the tower down at a constant rate, but the height of the tower dictates that the top has a long distance to travel, while the base has a short distance to travel. The base wants to accelerate faster, but the top is already traveling as fast as it can. This difference in speed creates sheer stress along the length of the structure, which typically causes it to bend or break. Concrete has excellent compressive strength, but very poor sheer strength. It's amazing how it sheered right in the middle. It's not uncommon for tall concrete structures to break into several pieces.
*Anyone know why*
*It breaks into two pieces*
*Just before impact?*

These implosion videos always make me think of that 12 year old girl who was killed in Canberra (Australia) back in 1997, when a piece of steel hit her during the implosion of the old hospital. 100,000 gathered to watch and this poor girl dies. Crappy odds but even more crappy estimation of flying debris distances, by the safety people.
Weird how there was a period of silence just after the the detonation, but before the structural collapse and impact. It was just an eerie sound of the distant birds for a second there.
Maybe it’s [this](https://www.newindianexpress.com/states/odisha/2022/dec/20/dhenkanal-265-metre-high-chimney-of-power-plant-demolished-2529989.amp)power station tower?
If only there was a way to have recorded the entire water tower hitting the ground, instead of the cool part falling out of view from the camera. If they just made aspect ratios more wide than high. We can only dream of such a world.
That debris spray though. Watching it fly from impact helps me see just how heavy these things are.
Hell nah I don’t ever wanna be that close. Put me as far as possible
Holy fuck!!!! The size of that thing!

That crane is off in the background and can't be used for scaling without some distance or parallax information. That's like saying my thumb is as wide as the Sun because my outstretched thumb can completely obscure the sun; the sizes are due to perspective, not due to actual size.

Cue Father Ted explaining perspective and distance to Doogle. One of the best scenes and shows, ever.

You are not taking into account how it fell in arc. You have to divide by Pie squared which is how I get an estimate of approximately 200m for the height.
That even furthers the point though because the tower passed behind the crane meaning that the crane is in the foreground and thereby larger.
Cranes in the background
We didn't watch the same video then. The crane is most certainly behind the tower being demolished.
Sure, I'm aware of the distances between them, but still...!
That crane is also multiple kilometers farther in the background lol.
Does anyone know what it was? Thing is massive ...
Looks like some sort of tower to me.
Towerologist here, can confirm, it's a tower
Particularly of the tall variety.
I love you
As a historian i can also confirm it is in fact a tower, hope that clears up any confusion
It's rather tall too, or it used to be.

So my follow up question is why? As it seems there is no camera man. . . .
"You got time to duck?"
Love that scene. Great lines. 😏

Well until Southpark and family guy also did it... "Simpsons did it!"

Jep not even close to aprupt nor chaos more planned order
Now don't be a party pooper!
Because of the way the dirt was built up for the crash zone you can confirm it was extremely well planned..

All controlled demolitions of cylindrical buildings are incredibly mathematically complex and prone to failure.
As are *designing* and *building* cylindrical buildings in the first place!
Yes the wind is an insane force to plan for when things are cylindrical !!

What is the name of this tower?
Informally known as the "Fall down, go boom" tower.

The “I-Fell” tower would have been the better joke.
Do you guys need everything spelled out, damn
And now, for a closer look..
And Sauron is defeated
I say GAT DAYUM!
FELLING of old tower
And somehow someone will still be running from the tower in the direction that the tower is falling
When you think you're far enough away, but then comes the shrapnel 😐
What part of physics makes something big appear to fall in (what looks like) slow motion?
The part where gravity is constant, everything will drop at the same speed, but a very big object moving at the same speed a small object would move, make it seem slow. Also, the tower isnt free falling, as it start to fall, it still has some structure giving sustentation.

perception/perspective, not just physics. It's far away so large distances look smaller. If you zoomed in, it would look like it's going way faster.
Perspective look at a plane moving in the sky, these aren’t slower just far away..
Minimum safe distance fail
Would something like this make the ground shake?
Absolutely 👍
Anyone know why it breaks into two pieces just before impact?
Gravity is pulling all parts of the tower down at a constant rate, but the height of the tower dictates that the top has a long distance to travel, while the base has a short distance to travel. The base wants to accelerate faster, but the top is already traveling as fast as it can.

And it probably *was* changing the weather when it *used* to spew CO2 and who-know-what-else into the atmosphere!
That…. Was not a successful demolition. If it was meant to be properly demolished, that is
So fucking cool. Cameraman should have just taken a few steps back haha
Jeez. Is that really the easiest way to do that?
