You guys have the best job in the world. The video quality is also top-notch; I really appreciate that you show each clip in its entirety, without annoying jump cuts in the middle; the bane of most videography these days. Subscribed.
*_Classic Physics Lesson..._* "The taller the chimney, the faster the top hits ground after falling in long arc"...That was a heavily reinforced concrete tube that didn't fly apart midair from lateral G's as it accelerated faster and faster the whole one way trip to ground from 250 feet up. I have seen other chimneys, especially brick ones break into sections well before hitting ground. They are built to support the dead weight of structure in vertical load only. As tube hit, compressed air trapped in tube gets squeezed out both ends as walls collapse. Most less reinforced chimneys, especially brick ones flatten into tiny bits upon impact. *_Classic Math Lesson..._* 250 foot tall chimney has an arc of 1/4 circumference of circle. C=2πr=2·π·250≈1570.8 /4 = 392.7 feet. Top of chimney traveled 393 feet before hitting ground. It was moving in both vertical and horizontal direction. That is why you see tips of chimneys and debris get launched far downrange from initial impact with ground... only thing keeping tip of chimney from launching like a cannon shell were the 2 steel flue liners getting a tight grip in tension... tip had already come free of rest of concrete tube before impact... *_Classic Demolition Lesson..._* Cut notch at bottom of chimney to move center of Gravity. Cut second notch at bottom of like ones used to fall trees. It determines direction of arc the chimney will follow on it's one way trip to the ground... *_Classic CDI Perfection..._*
@@JohnShinn6078 You’re right. It is for lightning protection. I searched Google for images of “Lightning Eliminators system on chimney” and found an exact photo.
Silly question… I understand the use of fence and geotextile fabric to prevent the debris to fly away at the explosion time but at the end, the fallen chimney became a pile of debris…. Even you can see in the video lots of debris flying everywhere….. and the surrounding area look to be free of buildings or facilities to protect….. so…. Why CDI didn’t use more debris or other material, instead fence & geotextile? (Sorry for asking, I always enjoy each of your published videos… but the doubt came out…)…. 👍👍
Production quality on the new videos is outstanding 👍
Thank you so much!
Yes, major agree. Thank you to the media folks who make these so well produced.
I love these videos.... Cheers for taking the time to produce and post them.
Glad you enjoy them! Thank you for supporting our channel!

Like a surgeon, CDI puts it right where they want it. Your videos are incredible to watch. Amazing work !👍👍
That sound is crazy
Always amazed by the amount of dust these demolitions create. Really enjoy the multiple camera views.
Glad you enjoyed the video!
Never gets old

@@JohnShinn6078 Your comment appreicated
wow the shock wave was big on this one
A merging of engineering, science, and art like no other.
Another beautiful job.... WELL DONE! I love watching your work!
Thank you very much!
I'm liking the new video format! Nice job!
Glad you like it! Thanks for watching!
This never gets old.
Amazing video, amazing channel ❤ Thank you !!

What's that on top of chimney? Is that to stop the birds nesting in it?
I was also wondering about that.
My best and only assumption is it's for lightning protection for some sort of sensitve parts at the top.

1:38 Bird: "Whutt?"
I love the roaring whoosh! Great videos.
Thank you! Thanks for watching!
Did someone see my chimney, it was here a minute ago😂
It was demolished-
Great videography
Thank you so much! Thanks for watching!
Another job great for the home theater and subwoofers. Love it.
The most amazing thing is that this is the first demolition video from anywhere in the US where someone doesn’t scream …. OWE M-EYE GAAAARD !

Legendary rockstars in their field. No wonder why. 😎
2:10 Chimney is Crazy
Bad-ass.
1:38 Yes Rico, Yes Rico Yes Rico... BOOM!
How much do you love your job ?
Yes !
its great to see gravity is still working.
Fred Dibnah weeps.
I hate you, you beat me to a Fred Dibnah first comment by one hour 😂
Cool!!
The chimney has fallen
1:50 the tree 😵💫🤮😵
TTIIIIIIIMMMMMBBERRRRRRRRRRRR!
who saw the bird at the top fly away
I forgot my safety glasses.
😵
😎😎👍👍💯💯
Dust suppression????????????????????
