Shrinking Serum: Sarah Leaves With the Serum

Sarah was shocked, to say the least, but not just because Karyn's body shrank to the size of a five-year old, but also because of what was in that bottle. She looked down at it and smelled the liquid, wondering what it was. But it had no smell. Was it water with some other ingredient mixed in? Sarah wasn't very good at science, especially chemistry, so she really didn't care about the liquid's composition. But she was *very* interested in the liquid's uses. "Tough luck, loser," Sarah said to Karyn, with a smirk. Then she left the restroom, and took the serum with her.
