how to burn using sunlight

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
