Thermite popcorn

Quick ... very quick.
  [vote for,

A small container with a pull-tab; pulling the tab ignites the thermite charge which pops the popcorn above it which then pushes off the lid allowing it to expand into a large paper or mylar bag.

Useful in emergency situations.

       //Quick ... very quick.// But perhaps not quick enough. Instead, what is needed is popcorn with a tiny detonator set in a half-millimetre hole bored into the kernel. All of the several hundred detonators are wired to a common source for _truly_ instantaneous popcorn.   

       For an additional cost, the detonators can be individually connected to a 500-terminal control box, allowing a detonation rate that matches the consumption rate.

       I'm afraid there's only one solution that would match 8th of 7's consumption rate.   

       But where does one find a sufficient quantity of U235 these days, now that North Korea's gone and tested much of theirs?

       You are correct. Be afraid... be VERY afraid...   

       // U235 //   

       No-one's built uranium devices for about sixty years. They're baby-steps things. All realistic gadgets are Pu-implosion, axially symmetric using pusher plates, and then fusion-boosted.

       You're still using those??
MaxwellBuchanan, Apr 22 2016

       No, of course not. We're just describing the primitive technology that fifth-rate dictatorships tend to knock together.

       well... you'd certainly be getting your daily iron and carbon requirement all at one shot.   

       How'bout an explosion-pumped microwave chamber.

       //All realistic gadgets are Pu-implosion, axially symmetric using pusher plates, and then fusion-boosted.//   

       I believe that from this statement (and a few assumptions) we can calculate the Borg's appetite for destruction - to a first approximation.   

       Apparently popcorn kernels pop at somewhere between 180 and 232 degrees C. Let's call it 220 degrees C. Let us suppose that the initial popcorn temperature is 20 degrees. So I found a table on teh internet which suggests that popcorn's specific heat is around 2 kJ/kg.K (2.04 air-popped, 1.99 oil-popped). We need to heat it up by the difference of 200 degrees, so that's 400kJ per kilo.   

       For the yield of the gadget from a fifth-rate dictatorship, I propose the yield of Ivy Mike (10.4 megatons TNT) as a reasonable approximation, where a Mt is of course 4.184×10^15 J. This gives an amount of energy available of about 4.4×10^16 J   

       Then we can divide through to get around 1.1*10^12 kg, or 110 megatons of popcorn, assuming 100% efficiency. In practice I suspect that a yield of 1% of that (a million tons) would be considered sufficient, and leave enough space around the fire for the borglings to roast marshmallows, and perhaps horse-chestnuts.
