Large 15oz Fruit Fly Mug for a High School Biology Teacher - Census Off by a Few Hundred

A bigger mug for the week the flies come out. The joke every biology classroom earns sooner or later, Fruit fly census: off by a few hundred., sits beside a clipboard of tally marks that refuses to stop at the margin, and the reverse shows the knocked-over vial with its escapees, each one a simple round body, two clear wings and a pair of oversized red eyes trailing a dashed flight line.

The 15oz size holds enough coffee for a double block of lab, a planning period spent recounting, or parent conference night. It makes a thoughtful thank-you for a genetics-unit veteran, a retiring science teacher, or an old lab partner who still talks about the escaped flies, and it works as a pen cup on the lab cart too.
