No idea what's it's made of. Some sort of extremely thin yet absurdly
strong plastic, but beyond that I couldn't say.

The spool is developing a kind of "cracked earth" pattern on its
surface, and there's some ferric oxide floating in the liquid now. But
beyond that, the spool and tape both seem as rock-solid as ever.
Perhaps I need to actually unwind the tape from the spool. That'll take
a seriously long time though; IIRC, there's about 8 km of tape in there! o_O
