Burning Leaves

If there is a sunny day and you have a magnifying glass, you're in luck! All you need is a spot in the sun and a dry leaf [the drier, the better]. Use the magnifying glass to direct the sunlight at the leaf. Soon it will burn! It might even catch on fire! It doesn't take long at all to start burning. Use as many leaves as you want!

Try it yourself and tell me about it.
