NOT GREEK FIRE, BUT IT'LL DO:

`Hellbrew' is cheap, simple to make (CHRISTOPHER MAUGHAN, 8/11/06, Toronto Star)

Anyone with half an hour, a set of instructions found online and about $75 can easily make the stuff.

"You could make it in your kitchen," said Prof. Bhibou Mohanty, an explosives expert at the University of Toronto.

Mohanty said the major ingredients are peroxide, which is found in hair bleach, and acetone, which is found in most types of paint. Mix them in the right quantities, use some aluminium powder to increase potency — and you've got yourself a ready-made bomb.

The compound has advantages beyond its simple makeup. For instance, said Mohanty, it's really easy to get it to explode.

"It can be ignited, as opposed to detonated," he said. That means that a simple match or lighter would be enough to start an explosion.

Because it's a liquid, it can be stored in places where airport security officials might not look. Thompson said just a small eyedrop container could hold enough of the solution (properly mixed, of course) to bring down an aircraft.
