Very interesting getting fire from the reflector of a car headlight from the Sun.
This effect can come in handy when making a fire or just set fire to something.
Especially when there are no matches, no lighters.
In a clean reflector in the center, put a piece of crumpled paper and direct the reflector towards the Sun.
After half a minute, the paper will fade and flash. Thus, you will have the opportunity to make a fire.
