The bottle holds the amount of water it would take to stretch one light
year, if all the molecules were laid end-to-end in a single file line. The amount of water it takes for that monomolecular line to reach
0.1–0.9 of a light year are also marked, as are a few other curious
and unusual volumes.

Not available for purchase as a standalone item.
