Wooden sticks as columns and beams, tape for fastening, and stiff paper for floors. Not shown-- I tried taping steel bolts to the columns to give them more weight to drive a collapse, but the structure fell over before I could finish attaching the extra weight. I removed the bolts before taking the picture.

There is a real problem making a structure that could completely possibly collapse under its own weight, and making a stable structure. I have been trying to make flimsy structures that might collapse, but they won't stay upright long enough to test their collapse response. This thing fell over before I was even done building it.

1) it is impossible to make a stable structure that can crush it's own structure,
2) there is some aspect of scaling down that makes it impossible to make a small stable structure that can crush it's own structure, and that a much larger structure CAN in fact crush it's own structure.

One other potential issue is the difficulty of getting the structural members aligned perfectly with crude fasteners such as tape. If I were able to align the tower more perfectly, it might be more stable-- though I doubt this would overcome the basic problem I described.

I love this blog. I try to find every collapse model on the web.

I know it is IMPOSSIBLE to smash components without explosives.

Hovever, here is model without pulverization / smashing components.

If people could see how hard it would be to make those cards smash in to pieces while falling.

I think the KEY issue to 911/WTC is that THERE is NO WAY of SMASHING components WITH GRAVITY.

Even a tower of wine glasses would not collapse before hitting ground.

a card house wtc: WITHOUT ANY hard or fragile components (no smashing components in to pieces)
(these cards should smash into pieces while falling) (make tower from glass and it still won't happen)

more accurate models:

tower build from glass:
smashing of hard & fragile material 1. :
smashing of hard & fragile material 2.:

omg then how they did this?:
from top to the very bottom!

Anonymous one - "I think the KEY issue to 911/WTC is that THERE is NO WAY of SMASHING components WITH GRAVITY."

This quoute confirms for me that you are an idiot. We dropped a steel beam onto some bricks the other day. The bricks were pulverised. How did that happen? Gravity was the only force.

If you truely believe your statemen t to be true, then you can safely sit beneath a 10ton block of steel and let it fall onto you. You belive that you will survive, because garvity can't smash components.

And spooked I ahvea third conclusion for you: You have no understanding of structural mechanics or physics, hence your model will not work.

buka001,so you think WTC was HIT BY A steel HAMMER?

Then that hammer should be fist attached to top of WTC and BEND after smashing all floors.

Just TRY to collapse something into dust like WTC without explosives.

The truth is known.

The WTC was brought down by the great Collapsing Hrung, lastr seen on Betelgeuse Seven.

The sole survivor of that disaster is a man named Ford Prefect.

He has all the answers.

Nice work spooky -

Tell me how you calculated that paper is a suitable analogue to concrete in your model.

When was the last time you saw a piece of concrete floor that you could fold, twist, crush or impact upon in anything like the same manner as "stiff paper"
