Fashionably late neutrons t-shirt

Some particles burst in right away. Others arrive late and save the reactor.

This shirt celebrates the delayed neutrons — the cool, calm, and stylish MVPs of reactor control. Sure, they show up late, but without them, the system goes supercritical. Sound like anyone you know?

Perfect for nuclear students, engineers, and anyone who believes being late is just part of the process (especially if you’re fission-famous).
