Wilderness Survival - Fire From Water

The basic idea is to take a piece of plastic wrap (Saran or otherwise) and form it into a "pocket", i.e. bring the four corners together.
The pocket is then filled with water.
The corners are then grouped together and twisted until the whole assembly resembles a sphere. This creates a makeshift lens.
Notice the upside-down foot in the "lens."
