Survival Glue

If the need for a strong glue arises and no modern options exist, hack your own using crushed charcoal and pine sap(=tree juice). Start by sourcing(=collecting) pine sap from the pine tree. Often you can find this sap in the form of dried clusters on the exterior of the tree. Look for wounds the tree may have suffered and collect the sap that oozes forth(=seep out) there. Next, melt the pine sap over the heat of a fire in a small metal container or in a depression(=pit) on a hot rock. While the sap is melting, crush black charcoal from the fire pit (the black chunks, not white ash) into a fine powder. Mix the powdered charcoal into the melted pine sap — 1 part charcoal to 3 parts pine sap. As this sticky mixture cools it will harden into a very strong natural epoxy that can be used as a glue substitute(=instead). The leftover dried glue in the metal tin can be reheated later to be made pliable(=flexible) once again and used indefinitely(=with no end).
