Hot-rodded them up!
So... I don't know what I was googling when I found (really. someone really needs to keep a closer watch on me) platinum-catalyst impregnated cotton. Remembering reading up on the handwarmers, that's kind of what they use in those. I bought a baggie-full, (which seems to be many lifetime's supply worth) for $5.
It's a bag of fluffy gray cotton. It's probably not dangerous. I didn't wear latex gloves. Didn't hurt.
The heads of the zippo warmers are little cotton-ish pads (the jon-e-warmers have a woven metal-thread head). So, because science, I stuffed the heads full of platinum cotton.
I filled them up with fluid, and took the lighter to them. This stuff GLOWED! I put them in my pockets and went to work...
It seemed like they didn't work near as good as normal. huh.
That night I pulled the cotton out. I took the springs from some clicky ballpoint pens, and, with a toothpick, stuffed them full of the cotton. As much as I could pack in there.
The springs fit right into the zippo head. So, it wasn't packed tight, but it was in there. I took the lighter to it. GLOWAGE X3!
These things got twice as hot as normal. Which is good. I think.
That might be how Chernobyl started.
Don't touch them when they are just bare metal, too hot! I found some baby socks, I put them in, in my pockets.
Platinum, burning unspent fuel, in your pockets, is probably ok. The package didn't tell me to not do that.
A bigger spring will fit in there, as soon as I find some. I've got enough of this stuff to go around. Fukushima.
Somewhere, there's a baby with cold feet.
