Hello and welcome to the forums

It sounds like you've chosen the proper materials that will combust, but have you checked that your "clicker" is actually creating a spark? You might have to do this in the dark to see if a spark occurs. If you're getting a spark, and using a combustible material, it should work. Could you post a picture of your apparatus?

Best, Keith
