One emergency method of lighting a fire used to be to break the glass of the light bulb in your flashlight and burn the filament, no more no less than the way its done with a strand of steel wool for example. Now, when you put the filament between positive and negative there will be some resistance in ...

A good burning barrel needs holes near the bottom to supply air. A pick axe or a geology hammer works well for putting in the holes. Put most of them between 6 and 12 inches from the base. Used for burning trash on a weekly basis a barrel lasts for years. If you store it where it is dry, it will last longer, as the alternation of heat and wet causes it ...

The simple answer is - no. Safely igniting a fire relies on controlled combustion. Improvising ignition out of a device like this is not going to create the sort of controlled combustion I associate with safety. If you can ignite the hydrogen byproduct you are more likely to get an explosive reaction that is both unsafe and unlikely to light your tinder ...

Hydrogen gas doesn't spontaneously ignite, but does burn in air over a wide range of concentrations. It's also ready to ignite with a spark. So although you may be able to start a fire with one, the source you quote is almost irrelevant on that fact. Hydrogen can also be given off when charging lead acid batteries - not a hot process indicating that has ...

Yes you can. Well... sort of. You can open the bag and use the magnesium powder (its a mixture really) inside as fire starter (think the classic old photography flash kind of effect but much much less violent and spectacular as that mixture would be a slow burning one) or you can light the hydrogen mixed with steam that comes off the bag when the reaction ...
