Call a chemist or cat wrangler.

I think that would work. If my research is correct the WetFire is powdered magnesium trapped in a cube of thermosetting plastic. Be warned that when you do open the original packaging and start breaking the tinder into smaller chunks whatever magnesium is exposed to the air will quickly be rendered inert. I think you are better off coating the intact cubes with wax rather than breaking them apart.

Also, I would use a fairly flexible wax like the stuff used to coat cheese rather than brittler waxes.

Thanks a lot for the info, Blast!

I just looked over each foil packet of replacement tinder that UST sent me recently... I can't find any obvious seam or packaging failures on the individual cubes.

When stored in an airtight container (such as a Lock 'n' Lock) the WetFire tinder seems to be offgassing some sort of byproduct. It collects on the wall of the plastic container and leaves a cloudy, slippery film. The smell is definitely of the chemical variety. I'm assuming since the tinder is non-toxic this is nothing to worry about.

This offgassing happened with the original batches of WetFire that had seam failures, and also with this newer batch with no seam failures.
