Concrete Experiment
Abstract:
This experiment is to test the hypothesis that concrete pulverizes in to dust
when it falls, as claimed by the official 9/11 Commission Report about the World
Trade Centers. If concrete turns to dust so easily, the world needs to
find a stronger, non-exploding building material. Blocks of concrete were purchased to fall from a 5th floor
balcony. It was found that the concrete cracked, but did not create a
significant amount of concrete dust. Thus, this ground breaking study is a Myth Buster,
as well as a concrete buster. We need a new investigation commission, with scientists not
politicians, to find out what really happened on September 11, 2001.
Purpose: To test the hypothesis that concrete pulverizes in to dust
when falling on to other slabs of concrete, as it did at the World Trade Center sites on September 11, 2001.
A literature review did not locate a similar study, so we decided to do this
ground breaking, or at least concrete
breaking, study.
David Ray Griffin PhD, speaking at the University of Wisconsin, said:
"Try this. Get a piece of concrete and drop it, a little over 1000 feet, and see
if it pulverizes in to very fine dust. It won't happen."

Materials:
Balcony, video camera, 2 concrete blocks (top and bottom). The original
plan for the experiment was to use concrete blocks with
nano-thermite explosives in it, as was found in the
World Trade Center dust. The Home Depot staff
did not know of any in stock, nor when they might have any for sale. So the
experiment had to be done with regular standard concrete slabs.
Methodology: A concrete landing block was placed at the bottom of a balcony at a condominium complex. Another concrete block would be dropped on top of it, from a distance of 50 feet, or 15.24 meters. The fall was recorded on video for the scientific community to review.
Safety Precautions: For anyone who replicates this experiment, be sure to
remember "safety first before science." An orange safety cone was placed
on the side walk to warn possible pedestrians. A watchman was posted to
make sure no one walked in the way during the experiment, especially the Condo
Manager or Security. A concrete block was dropped from the 5th floor
balcony and the results were photographed.
Hypothesis: It was hypothesized that the concrete would completely pulverize in to clouds of dust, as was found on 9/11. The contrary hypothesis of "Truthers" is that there should have been a stack of concrete floors, like the buildings that collapsed from an earth quake in Ahmedabad, India.
We would expect to find that dust will blanket the condo grounds, without any large chunks of concrete. Only a small broom, dust pan, and possibly a vacuum cleaner should be necessary for cleanup. This experiment should replicate the events of 9/11, and confirm the conclusion of the official 9/11 Commission Report.

Calculations: The concrete fell 5 floors, at 10 feet per floor, for a distance of 50 feet, or 15.24 meters. The rate of fall was approximately 32 feet per second per second, or 9.8 meters per second squared. The duration of the fall was timed at about 2.1 seconds. At impact, the concrete slab was traveling at a rate of 64 feet per second, or 43.64 miles per hour, or 70.23 kilometers per hour.
There were large pieces of concrete, and only a small amount of concrete dust.
Conclusion: Despite the hypothesis, and the conclusions of the official 9/11 Commission, concrete does not crumble in to dust when falling on to concrete, at least from 50 feet. A replication study should be done with the same thickness of concrete that the World Trade Center had.
Therefore, we have "concrete evidence" that the Official Conspiracy Theory (OCT) of the 9/11 Commission was not scientific, and contained errors that can be shown by simple home experiments. It indicates that the Government is covering up something from the American citizens. The conclusion that concrete does not pulverize without explosives, based on an easily replicable study (simply drop a block of concrete and see for yourself), is on solid ground.
Some other explanation is needed to explain the voluminous clouds of concrete dust found at Ground Zero. One explanation that explains it perfectly is controlled demolition, using pre-planted nano thermite explosives in the World Trade Center buildings, during the largest elevator modernization project in history done by ACE Elevator Company under the supervision of SecuriCom security services during the months up to 9/11/2001. We verified at Home Depot that it is not easy for terrorists to buy this controlled explosive substance. Further experiments and another formal 9/11 investigation should focus on that explanation.
