It doesn’t have to melt, you fool.

I do believe that it’s the first time in history that fire has ever melted steel. I do believe that it defies physics that World Trade Center tower 7—building 7, which collapsed in on itself—it is impossible for a building to fall the way it fell without explosives being involved. World Trade Center 7. World Trade [Center] 1 and 2 got hit by planes—7, miraculously, the first time in history, steel was melted by fire. It is physically impossible.

Popular Science, whose editors wrote the book Debunking 9/11 Myths, do just that, shooting down Rosie’s televised conspiracy theories about WTC 7. Specifically, in this case, the structural steel didn’t have to melt, just weaken enough to no longer support the weight of the building.
