Dr Blevins is once again using misdirection to thwart attempts at critical thinking. I'll give an example in a second. But of course she's not expecting to trick any of you for long - she doesn't need to - for her hoax to work, she just needs to present her pseudoscientific bafflegab to gullible truthers, who, as we know already, lap up pseudoscientific babble like koolaid.
Dr. Babs already knows that Judy Wood's nemesis, Dr Jones, has had quite a bit of success with his nanothermite hoax, so she must be somewhat encouraged to try her hand at the game. She knows Dr Jones is wrong, yet he's a big celeb in 9/11 Truth circles.
You must keep in mind the desperation and lack of scruples already displayed by Dr Babs; the cryptic refusal to answer many legitimate questions, the obvious delusions of grandeur which fuel her actities etc.. but even if we reflect on her own words regarding her past hoaxes, we can learn a few things:
from her
blog
'so I came up with a scam'
'I kept creating all these hoaxes and scandals around London'
So we already know Dr Blevins is fond of hoaxes and publicity stunts. But returning to her misdirection - somehow, in a discussion about WTC Dust, Blevins manages to redirect the conversation to a missing tail section of flt 93 at Shanksville?
Not in this lifetime, and not in this universe is that relevant to the composition of her questionable dust. Yet you can almost guarantee she'll bring the subject up in her Dec 01 hoax presentation.
Has Dr Blevins responded to demands that she detail the provenance or composition of her dust? Absolutely not. She does refer to the 'candy' she promises to presnt at her little Bleeker talk tho. God only knows what fresh nonsense this will be.
Getting back to the good doctor's claim about dustified steel, she has repeatedly moved the goalposts of her claim. First she insisted that 'Almost all' the WTC was dustified.
Of course, she refuses to properly quantify this claim - it's just so inconvenient, isn't it?

But when confronted with the truth, she now realizes she must account for the many pictures of strangely and stubbornly un-dustified steel, and the documentation of at least 200,000 tons of steel recovered. So now she allows that not all the steel was dustified. Wow, now that's genius-level science, init? C'mon, Tracy, that's grade-school level rationalization.
Your real problem is that out of all the dust collected and tested by competent labs, iron wasn't the main constituent. You'll never be able to deal with this fact - and it directly contradicts any claim you've made, since it shows that the materials which were pulverized were ordinary building materials, not steel.
You also falsely claim that gravity had little to do with the non-collapses of the towers, yet it was demonstrably gravity which provided the force to pulverize the building materials, but oddly not the steel rebar and beams, which survived fairly intact.
The worst obstacle for your hoax is that there is zero, and I mean not a shred, of evidence of a steel beam which has been partially 'dustified'. Since you've already allowed that only
some of the steel was dustified, then there must be a boundary to the effect, and there must be an artifact of that boundary on remaining steel - else your theory is incorrect.
It's very simple logic, really. So not only is your theory inconsistent within itself, it's not consistent with the observed evidence. In short, it's already a failed theory, and that makes your efforts pretty weak.
Reflecting again on some of your past behavior, you have a history of attaching yourself to important events or issues. You are a chronic attention-seeker, willing to pull outrageous stunts and hoaxes; you were attracted to 9/11 way back, and went so far as to offer sexual favours to FDNY personnel who suffered during the terrorist attacks - as pathetic and disgusting your behavior has been, we can see that you haven't changed much - you still seek to exploit this tragedy for your own narcissistic reasons, pretending to be providing a service to society.
Yuck!!
