Metable Wire around a Resistor
This is the way to have a self destruct circuit (mission impossible) on a device. The simplest way is to have as the following (from Amp Hour 679):
Dan Esparon: Yep. That's pretty much it. Right. As far as I'm aware. At least that's what the test pods look like. Yeah. Very low tech. Very reliable.

I'm not sure what wire is used, or if it's the same as fusible wire / fuse wire / fusible links, which are found in the automotive industry.
