The White House and U.S. National Institute of Standards and Technology (NIST) are urging Americans to return to the stone age for their own safety.
"After discovering that 'thermal expansion' of steel from a low-temperature fire led to the collapse of World Trade Center building 7," said NIST spokesperson Noh Wei, "we started realizing that other metal objects might also be at risk".
So NIST scientists tested other metallic objects using state-of-the-art computer models. The models predicted that every oven and barbeque in the country could disintegrate at any time, leading to a progressive collapse of entire houses.
"We also determined that car engines, airplane engines, and boat engines could all suddenly fail due to thermal expansion," said Wei. "Indeed, we soon realized that almost all industrial processes could lead to catastrophic failure, other than, perhaps, those used in freezers."
White House spokesman Phil Johnson agreed, saying
"Once you understand this principle of thermal expansion, you start to realize that even household showerheads and faucets are dangerous. The hot water flowing through them could wreak havoc. The President is committed to leading the way back to a safer time, and a return to proven, traditional materials - which may not be flashy like metal - but remain rock-solid even when warm."A Fact Sheet from NIST provides recommendations and safety guidelines based on the new thermal expansion discoveries:
Is Metal Safe?
While it was previously assumed that metal was safe, scientists have now discovered that steel and other metals can suddenly fail due to exposure to heat. NIST urges everyone to stop using metal, and to reassess possible replacements with stone materials.
Sunlight can warm up metal. Therefore, no metal should be used where any sun exposure is possible.
If people choose to continue using metal, we urge them to live underground, to protect against the dangers of sunlight.

Two Powerful Forces Should Have Made WTC 7 Tip Over
World Trade Center building 7 was not a square or a rectangle, but a trapezoid:
As such, the larger side of the building would be heavier and more massive.
NIST claims that column 79 collapsed, leading to the collapse of the whole building.
Column 79 was located towards the larger end of the building (towards the bottom of the following diagram):
Because NIST claims that only column 79 was destroyed in the beginning of the collapse sequence, and because the same side of the building in which 79 was located was the bigger, heavier side of the building, two different influences should have ensured that the building tilted toward the bigger end.
Therefore, high school physics shows that - if column 79 had collapsed and explosives did not take out all of the other support columns at once - building 7 should have tipped towards one side.
NIST’s argument that the strong exterior steel held the building perpendicular and didn’t let it tip over is illogical. The forces generated by the two above-described processes would be larger than any dynamic NIST describes. At the very least, the contrary forces would have been visible, and there would have been buckling, swaying or other indications of competing forces.
NOTE: If the collapse had started at the base of the building, then perhaps the wider base on the larger side of the building might have compensated for the greater weight. However, NIST states that the collapse started at the thirteenth floor. The wider base should not have offset the greater weight and failure so high up - from the 13th floor upwards - at least not entirely. In the absense of explosives, we still should have seen substantial deformities, buckling and/or tipping.
I encourage physicists and engineers to estimate how much heavier the larger side of the building was than the smaller side, and to calculate the forces which would have been at play given the hypothetical collapse of column 79.http://factsnotfairies.blogspot.com/search/label/Two%20Powerful%20Forces%20Should%20Have%20Made%20WTC%207%20Tip%20Over
