How to start a fire with a coke can and chocolate bar

Wildwood Survivor has some detailed information on how to start a fire with just a coke can and a chocolate bar. Here is a summary:

The key to this is the bottom of the coke can (by the way, any pop can will do), which is ideal for reflecting and concentrating the sun's light and energy.

The can bottom is not shiny enough to function as a good reflector and concentrator of sunlight. It needs polishing. The chocolate does an excellent job of this. So, simply break off a piece of chocolate and use it to polish up the can bottom!

On a sunny day (yes, you do need sunlight!), Hold a piece of suitable tinder, such as a fragment of tinder fungus, at the focal point of the can bottom -- about 1 - 1.25" away from the center of the "bowl".

After a very short time (only a few seconds in the bright sun), the tinder fungus will be smouldering. Then transfer it to a tinder bundle and blow it into flame.
