one thing about PyroFuze

I've mentioned before that if the battery was a big 1.5v battery, it would be marginal for it to detonate a blasting cap without some additional circuitry to get a higher voltage.

Similarly for PyroFuze...it won't ignite with 1.5v I believe.

So if Cooper was building a real bomb, and using PyroFuze, why would he have a battery setup that wouldn't work?
(assuming he had a big 1.5v dry cell. (I would think you'd need 9 to 12v)

Blasting caps use a small diameter resistance wire (sometimes called a bridgewire) that is surrounded by a small amount of primary explosive material. An electrical current is forced through the bridgewire, triggering the explosion of the blasting cap which then initiates detonation of the main explosive charge(s). When very precise timing is required, a high current capacitor discharge is often used to cause the bridgewire to explode. Blasting caps only require about 3 to 15 milliJoules of electrical energy to reliably detonate, and the typical resistance per blasting cap is only 1 to 3 ohms. Although lower currents can trigger caps, a minimum current of 0.5A is typically used. Higher current pulses reduce the time delay between current application and detonation.

1.5 volt battery's were made way before 1970. they date back in the early 1900's.

Shutter, yes those numbers make it sound like 1.5v is enough.

But in the same Quora post you quoted, if you scroll down, another user says this (below in courier)
If you only have 1 cap, a simple 9v battery can probably send out enough current for the amount of time needed to ignite a blasting cap...Or a 6 volt lantern battery would be better.

Just seems like a 1.5v battery is unnecessary risk to not explode.


Three volts at the lead ends will detonate a cap, but at least six volts is needed to be reliable.

Electric caps are sometimes used by cavers to crack rocks when a tight spot in a cave needs to be enlarged. A 9 volt battery is the common power source. A single 9 volt battery has enough charge to detonate a dozen or more caps.

My 1.5 volt dry cell sure lit up the glow plug on my .049 cubic inch Cox two stroke model airplane engine. I replaced it in 1962 with a Nicad wet cell that was surplused from Nike Missiles. They were heavily advertised in electronic hobbyist magazines. That used wet cell was just amazing. I beat the hell out of it forcing fast charges hooking it up to my HO train transformer and cranking up the voltage. I must have gone through hundreds of brutal charge cycles with high heat, bubbling electrolyte and all that. I found that wet cell thirty years later and although the plates were crusted in mineral salt dendrites, it still took a change and held it.

looking at the dates these type of batteries were used makes you wonder if the battery he had (if it was this type) was even any good?

What if the bomb wasn't fake? Sure puts a different light on Cooper. I think it was fake, but cannot say for sure.

Blevins has a witness who says she saw KC making what appears to be a fake bomb using stacked quarter coin tubes wrapped up with red electrical tape. She also mentions a clock which I do not think was seen by any witnesses in NORJAK.

Good question. These old carbon-zinc dry cells had a pretty short shelf life.

I firmly believe it was fake...

I'm bothered with the quote the made about not using the radio because it could set off the bomb. I think this was two bluffs for one. first he tried to get the communication down, and second saying the bomb could be triggered. that couldn't happen if he had the circuit open or wired in a series.

were they even manufactured in the 60-70's?

More "super memory"

Robert is going off a description the Cowlitz sheriff gave in his notes saying the bomb had red tape on the sticks..they mention red wires and tape in the 302's..

No, there's a fbi memo with the red plastic tape. Snip below. I'll post the full too.

here's the fbi memo where there's an interview saying the bomb seemed to be wrapped in red plastic tape.

if so, that just seems fake to me. Easier to get black tape at a hardware store if you're making a bomb?

why use red? to make it look more real??
