Millions of people believe that the World Trade Center was demolished with explosives as part of a vast government conspiracy.
One of the core pieces of evidence for this belief is the presence of millions of microscopic iron spheres in the WTC dust. It is falsely claimed these microspheres could only have come from the use of explosives, and so their presence proves controlled demolition. Why does this false belief persist after being debunked over a decade ago?I explain the misconceptions about iron microspheres that keep the belief alive, and how to discuss these misconceptions with 9/11 conspiracy theorists. I’ll show where the WTC microspheres probably came from. There will be a live demonstration of one method of making iron microspheres using materials from the hotel gift shop, along with quick descriptions of ten other methods the fire marshal won’t let me show.
