You guys would not believe what I learned yesterday! The story goes like this: 10 months after 9/11 I met girl in Chicago who was in NY days after the towers collapsed,she was so shocked at what happened and she is very patriotic may I ad, that on her return to Chicago area, she took with herself ziplock bag full of dust and rubble from the WTC to remember this day forever---(Women are so sentimental) When I met her and she told me what she has done, She started crying and stuff, and I was really attracted to her so we you know went to her place and had hottest sex ever!!! That girl told me also that she is studying chemistry at the University of Chicago, so at that moment lights started flashing in my brain.I am not big conspiracy guy ,but i have read all possible explanations why the towers collapsed.Some people think the towers were destroyed by controlled explosions. So I asked her many times if she would not be able to make analysis of the dust particles if they not contain any traces of explosive particles .Finnaly after months of begging on her day off she managed to run gas chromatograph or spectrometer analysis(I don't remember exactly) and well... Bingo.There are traces of explosives!!
