Resublimated Thiotimoline
From Jenny Everywhere Wiki
A “small and badly cracked plastic jar” containing Resublimated Thiotimoline was one of the items Jenny and Kim once found when cleaning out their apartment's closet in one universe. Though it contained just a few cc of liquid, they decided to dispose of it in an uninhabited universe, like the Reality Bomb they'd also found. (PROSE: Cleaning Day)
Behind the scenes
Thiotimoline was a fictional chemical with time-bending qualities, invented by Isaac Asimov in a 1948 spoof academic paper entitled The Endochronic Properties of Resublimated Thiotimoline, and used in several follow-ups. Thiotimoline has gone on to be referenced by many other science-fiction writers.
