I would like to try to do an investigation on the seemingly magical TSA strips that can detect explosives after being waved over liquid flasks. Data I have found are:
A picture of the product on slide 12 of these presentation (powerpoint download alert). Can anyone enhance the image to see something on that label?
The strips should be held above the flask for 5 seconds (same presentation).
After being held over the flask, strips are "developed" with a few drops of distilled water (
info from TSO Dean).
Reading is a simple visual change in the strip.
Anyone else have any more information on these tests? Maybe we can solve a mystery together! Or maybe they really are magical...
