the human equivalent of a flask of nitroglycerine

Well, I did mention spontaneous combustion further down the entry :-)

(If I wanted to be a suicide bomber, I wouldn't have to carry any dodgy stuff through airport security. Just get me to the target area and give me a bread roll, a pint of beer and a cup of coffee; I could mix well, down in one, and *boom*. Adding cannabis as well would probably make me near-thermonuclear, but that starts to get back to the airport security issue; although I suppose if I ever conceive a desire to nuke Amsterdam... :-)
