Large Science Fair Mug 15oz - Which Paper Towel Is Strongest, Twelve Times

"Science fair night. Judged twelve projects on which paper towel is strongest." A 15oz mug for a long night of judging. The art lines up a dozen tri-fold boards across the gym, every project testing the same thing with a wet sheet and a pile of coins, and one judge with a clipboard and a smile that never quite slips.

Room for refills on fair night. A gift for science teachers and judges. This is the larger 15oz mug.
