Jeez Turbo, you're nearly there but I'll have to come back tomorrow since you obviously need time to focus on the actual question. The cards were secure enough to hold the structure upright, stable, and resistant to air currents and impacts. So how did the top two/three storeys of the tower destroy all fifteen storeys below?
How can a light object completely destroy a heavier one?
I have no idea why there's this new precondition.
Still, you have no clue.
The cards or "STOREY" you speak of does not exist.
The video does NOT show an entire section falling at once.
The cards are falling individually like dominos.
The cards themselves are fine. In other words, one card falling on the
other did not cause the other card to break!
Just like dominos falling over, they don't break apart from tipping into
the other.
The towers were an assembly welded and bolted together.
The cards were not bolted/welded/taped/glued/etc. together.
