Chaperone (verb): Science Definition T-Shirt with Black Lettering

Robert Brown discovered it, Einstein explained the math behind it, but only a middle school teacher has truly lived it.

This shirt captures the essence of the "random walk"—otherwise known as trying to get thirty 13-year-olds from the bus to the museum entrance without losing one. Featuring a bold, streetwear-style definition on the back and the classic Prof E. & Ellie’s logo on the front, this tee is the ultimate uniform for field trip season.

It is designed for teachers, brave parent volunteers, and science nerds who understand that students in a public space behave exactly like microscopic particles: erratically, spontaneously, and with zero regard for straight lines.

Because while you can't predict their path, you can at least scientifically explain why they just bounced off that wall.

Why you’ll love it:

+ The perfect inside joke for your next museum or zoo field trip

+ Modern, high-contrast typography that commands attention (even if the students don't)

+ Ultra-soft fabric to keep you comfortable while doing headcounts every 45 seconds

+ Original Prof E. & Ellie design that proves physics applies to everything—even 7th graders
