Making fire with a condom

While teaching fire craft at the World Scout Jamboree earlier this year, the most popular method of firelighting proved to be fire by condom.


Basically you put some water into a condom and tie the end. Then you manipulate the condom to form a lens shape.


Once you get the shape correct the result is instant. Personally I favour Crampball Fungus for this method of firelighting.

I've just found this video which demonstrates the method rather well.
