There are several self-heating self-contained meal systems available and they are very useful for the camper, hiker and, of course, the airsofter.The smaller airssoft fields have a rather sad reputation for thier universal lack of facilities, and in particular for being bereft of a 'mess tent'. So I have tested out a couple of self-heating meals as a moral boosting alternative to the usual cold lunchbox or sandwich pack.This video is a demonstration of how to use these two meal packs - the HotPack and HotCan self-heating systems. www.milgeek.co.uk Less
