Large High School Physics Teacher Mug 15oz - Egg Drop Day. The Custodian Already Knows.

A 15oz mug for the most dramatic lab of the year. The slogan "Egg drop day. The custodian already knows." wraps around a tall stairwell scene: three student contraptions mid-fall, a parachute egg, an egg in a straw cage and a taped box, and the custodian waiting below with a mop, a yellow bucket and the smile of someone who has done this before, one little splat at his feet.

The bigger size holds plenty of coffee for a full day of drops. Give it to a physics or physical science teacher, or to a school custodian as a thank-you for every egg drop cleanup.
