PVC? Hard to get any decent pressure to make ….well, either you understand or you don’t. I’m not gonna give any clues. Coiled wires leading to a box from the ends? Yeah, it looks like a movie version of a “bomb”…meant to be seen and identified when the package was X-rayed. I’m surprised they didn’t write “Bomb” on the side in bright red marker just to make sure that it would be identified properly.
Plus of course the “timer” as means of detonation. I’m surprised they didn’t use a “Baby Ben” alarm clock (kids, ask your parents)…..
Plus, of course, those 6 stamps…even though the packages were delivered by a courier, not the USPS.
But hey, it makes for good press don’t it? Lots of pictures and something for the Talking heads to talk about. And, of course, a mostly uneducated audience to believe.
