Tub with tail (or twit, originally from the acronym) is an 8-cell still life composed of a tub with a tail that was discovered by Charles Corderman and Hugh Thompson in 1971.[1][2] It is notable for its use in eater 5.


Tub with tail is the twenty-eighth most common still life in Achim Flammenkamp's census, being less common than very long boat but more common than very long ship.[3] It is also the thirty-seventh most common object on Adam P. Goucher's Catagolue.[4]
