I know which one the evil stair is - it's the one that is attached to my back porch, that I slipped on. Fortunately didn't break anything, but not likely to fix anything, either.
But while people and their behavior may be fixed with evil stares, I've seldom found it effective on inanimate objects.
Maybe you haven't found a powerful enough evil stair, or stare?
