Challenge - never bring anything to start a fire

[Joe tahkahikew]

I saw one the other day on youtube, variation of magnifying glass. Using a clear plastic sandwich / freezer / zip lock bag, filled with water, seal and twist the top a lot. Twisting the top forms the bag into a more spherical shape then the water inside can be used to focus sunlight the same way as a magnifying glass.

Have you used it yet?
