E = MC squirrel

Some equations don’t need explaining. They’ve already been peer-reviewed by the local wildlife.

This tee delivers a clean, minimalist take on the familiar formula: E = MC² —with a small but important woodland correction perched exactly where it belongs. Quietly clever and confidently understated, it’s the kind of design that rewards people who notice detail, but don’t feel the need to make a big deal about it.

Perfect for science fans, introverts, educators, and anyone who appreciates humor that keeps a straight face.
