One of my chores at the cabin is to collect floating chunks of wood for kindling. We gather them in large plastic tubs. Over time, the plastic cracks. Rather than throw the cracked ones away (save that nail), we repair them with Duck Tape. That way we can get a few more years of good work out of them. In this one, I left the hole open so water can drain out as the wet wood dries.
Here's an interesting video about how they make Duck Tape.
