How was the WTC 6 pulled?, page 2

This is kind of interesting.

Explosives come in all sorts of forms--gels, granules, powders, cord, liquids, plastics (in blocks and sheets), and old reliable, stick dynamite. All have properties designed for specific conditions. Huge quantities are used every year, often in urban areas and often without anybody even noticing the detonations. Dynamite is a mixture of nitroglycerin, a liquid and a binder. It was the first practical high explosive and revolutionized mining and construction by making the blasting process safer and more efficient... As per the design, the first blasting takes place the weight of the structure will begin to pull the building down in a controlled direction. The remaining charges fire at preset intervals of about one second, fracturing the structure's internal supports, weakening it from the inside out. Then, as it falls, the once strong structure's own weight tears it apart leaving nothing but a pile of pulverized concrete and reinforcing rod.

So, how much dynamite does it take to drop a twenty-two-story building? Not much, if it is placed correctly. The design for the tall building uses a bit less than 200 lbs. Plus a small amount of 'det' cord. Actually, gauging the amount of explosive to be used is key to a successful drop.. The trick is using enough to be sure that the building comes down exactly where it is supposed to without excess flying debris or breaking windows with the noise of the shot.

Parts bolded by me.

First bolded: Comes in all sorts of forms. Notice the plastics. Could that be were the 1,3-diphenylpropane came from?

Second bolded: Notice it says without many people even noticing in urban areas. So, there goes the theory that everyone miles around would have heard the earsplitting explosions on 9/11.

Third bolded: Not much explosives need to be used when placed strategically. So much for the thousands of pounds of explosives. If it takes about 200 lbs. for a 22 story building, that is only 5 times more for WTC towers...making it only 1000 lbs....which I believe could have been done every 35 or so floors if need be...making it less. Plus all the hype (the photo that is always used showing a floor of some building with massive amounts of explosives and detonation cord) then goes out the window. Remember it said "small amount of detonation cord". Hmmm...very interesting.

Sorry to take this off topic of WTC6 but thought I'd share what I've found so far. Still looking for the "pulling" type of demolition to see what is involved in that.
