Cole’s Nailed Jelly

Given some jelly mixed according to standard procedures and a vertical wall, it is not possible to nail the former to the latter and have it stay there for any significant amount of time. Furthermore, these experiments were conducted by nailing the jelly to a horizontal surface which was then gradually tilted. Nailing jelly to a wall while the wall is vertical is an intractable problem in itself due to the difficulty in picking up jelly with the hands without it disintegrating — via Improbable Research
