IED in Brownsville

[230RN]

A simple pendulum switch, like they used to have on car alarms.

I was wondering to myself the other day, "Hmm, I wonder what I could use as a substitute for a mercury switch?  Perhaps, in a situation where it doesn't have to keep for too long, salt water?"

Ball bearings that if moved would find themselves completing the circuit would work I suppose.

Anything horribly unstable plus a booster charge if needed.

Nitrogen triiodide, as an example.

Considering how much I see the problem at work, just make sure a bunch of the terminations are very loose and make the detonator explode on loss of signal.  That way you don't have some Hollywood bozo rifling through the wiring trying to decide whether to cut the red wire or the blue.

Still doesn't prevent removing the detonator or clipping it's wires.

That all depends on how it is wired.

Has to beep too.

That steadily rose in tone and tempo.

[RaspberrySurprise]

We are now at the point that nothing even needs to explode, catch fire, or be destroyed at all for us to panic and spend thousands of dollars and hundreds of cumulative man-hours on resolving it.

Don't forget adding ever encroaching restrictions on liberty as well.

[Tallpine]

Has to beep too.

Plus the tense orchestra music.

[280plus]

Make all the wires the same color.

Salt water with enough salt dissolved in it to make it unfriendly to micro organisms might do the trick, in the right vessel.

Maybe salt water with shredded aluminum foil mixed in?....



...but I'm confused about your concern about micro-organisms....are you afraid the bomb tech might catch a cold?.....
