Flammable Glue

See the subtitle. Quite a few existing glues out there are flammable before they dry, but few are claimed to be especially flammable afterward.

This needs to be fixed!

For example, suppose you have a bunch of Old Important Papers that you can't let fall into the wrong hands. You don't need them any longer yourself, but they have data on them that you don't want others to mis-use.

Shredding isn't really the best idea. There was a Batman movie in which the Penguin restored a shredded document "with a little patience and a lot of tape".

Also, if you send the papers off to a "trusted" shredding company, which claims to do a thorough job by sending the shreds to a paper-pulp plant for recycling, well, just because they Claim to be trustworthy, how do you Know For Sure?

So, that just about leaves "burning" as the best remaining option --but it has problems, too. You don't want fire to convert the paper into rising cinders that can start fires elsewhere, after all!

So, enter Flammable Glue. You glue your Old Important Papers into solid masses of various sizes, and use them like fireplace logs. The glue keeps the papers "together" enough to prevent flaming/floating cinders from getting loose.

And, of course, since the glue also burns, it helps the fire such that nothing but paper-ash is left over when it's done.
