If you have access to water and a bit of plastic wrap or perhaps a clear plastic bag, with a little patience you can create a spark.
All it takes is a little ingenuity in containing the water and using it as a form of amplifier to capture light, in order to encourage a little spark.
A good method is to start close and back away until the beam is focused. After that, it should take a few seconds for the paper to smoke. Under certain conditions, an open flame can grow to an uncontrollable, blazing fire.Use of video content is at own risk.
