It's quite easy- take a magnifying glass and a dry piece of a paper ( preferably newspaper ) and go to a place where appropriate sunlight is available. Let the light of sun fall on to the magnifying glass. Bring the piece of paper beneath the magnifying glass. Now your objective is to move the magnifying glass up and down in such a way that the light emerging from the magnifying glass concentrates to a point. Hold the both things in the same position for a while, and soon you will be able to see the miracle, fire without a matchstick ! Enjoy!
