krampus, I would think that bigger heat dissipation area would be better at dissipating energy, given mass is very close. Perhaps I am wrong in some way, so yes, definitely looking forward to the video.

Up to a point, yes. Heat sinks made of aluminum do in fact use surface area to help dissipate heat. However, once the aluminum becomes too thin (ala a beer can, or aluminum foil) it becomes much more susceptible to melting.

So mass is important, but so is the configuration of that mass. Basically, melting aluminum foil with a match is "a trick". In general, that trick only applies to aluminum foil and things that are similar to aluminum foil.
