Here is how to start a fire using a plastic bag!

As children, we are taught that there are several ways to start a fire, but this is perhaps one of the most original, especially for the ease with which you can find the objects necessary to start a fire in an emergency.

In fact, what seems like just a simple plastic bag full of water can turn into a rudimentary magnifying glass that allows you to harness the sun's rays and use them to ignite highly flammable material like bark, dry grass, and small brittle twigs.

This is a nice experiment to do but without ever forgetting that the fire can be very dangerous!
