A fun fact about the colder seasons of the year in the Northern Hemisphere is that we are actually closer to the sun during these months of the year. This means that attempts to start a fire via magnification will be much more successful.

Watch the video below to see how you can use a simple plastic bottle of water can be used to light a fire for warmth.

Of course, this tip is only helpful if you carry a clear plastic bottle of water, and can only be used when the sun is at full brightness, preferably near midday.

While you can probably do this trick with a glass water bottle, you won't be able to reap the second benefit of this trick, that is, water purification.

UV purification only works with plastic bottles because glass blocks too many of the UV rays. But if your only goal is to light a fire, have at it!

This just goes to show that your biggest asset when out in the wilderness is your imagination and perseverance.
