There is nothing magical about a pressure cooker except that it can allow a really slow and crappy homemade explosive to build up enough pressure to actually explode.

The reason that they are apparently popular in Afghanistan and the like is that everyone cooks with them, so the sight of a pressure cooker in the car is not suspicious.

A pressure cooker operates in home-cooking, as I understand it, because it has a lid that is unlike any other lid used on a pot or pan. It clicks into place, and is clamped down until
its job is done. A roommate o* mine once splurged and brought one home so he could make his own tahini using chickpeas.
BUT regular pressure cookers ONLY operate like anything else on your stove, with a steady HEAT SOURCE underneath them.
So I don’t understand the use o* them 4 these kinds o* terrorism, which use no heat source and contained pressure.
I think they’re used because o* the tightness o* the lid and its containment o* what’s inside: in the terrorist’s case, explosives which are detonated electronically.
