Spray-on Explosive Detector

Man, and I thought that explosive detectors normally came in the form of highly-trained dogs or high-tech gizmos, but scientists at the University of California, San Diego have managed to come up with a spray-on explosive detector. This non-invasive method will glow blue under UV light in the presence of nitrogen-containing explosives, where its silafluorene-fluorene copolymer is sensitive enough to detect just a billionth of a gram of explosive. Now that’s really something and could prove important in the fight against terror as you never know when the next attack might come along and in what form. Also, this is pretty much an instant method of knowing whether things are going to go ka-boom around you.
