Magnifying glass, strike anywhere matches, fresnel lens, 9 volt battery and steel wool, potassium permanganate and glycerin, bow drill and / or flint and steel! ;-)
FWIW glue a piece of the striker plate material inside the cap of the match safe and insert as many matches as will fit upside down into the match safe so that the match heads are pointed away from the striker material. Close the match safe and the O ring should keep everything dry.

Warning! This is strictly a hypothetical and experimental method and is in no way a recommended practice. It probably violates some OSHA or NFPA rule or law.
If you decide to attempt this method / modification you could quite possibly be putting yourself at risk. Consult with a trained professional and do not try this yourself.
Party On,
