in ancient times our ancestors generally do not know lighters
a wide variety of ways to make use of fire to cook there
are certain stone rubbing to get the fire
This time I will share a new trick that may be
a new alternative that you can use when you
need a fire but you have no source of fire,
here's how to burn by using sunlight
first you should prepare is
a former photo frame or you can make it out of wood
use a thick plastic on a wooden frame heat resistant
place on top of the bricks or other heat-resistant objects
as the following example
pour a little water, such as in the picture below
then brought put straw or other flammable objects
just a few minutes will burn straw depending on the heat of the sun
please try as you will need this someday, hopefully this article helpful
