Abstract: A promotional writing instrument includes an elongated barrel having a writing end and first and second longitudinally adjacent transparent chambers. Translucent fluid substantially fills the first and second chambers, and a first object is disposed within the first chamber and a second object is disposed within the second chamber. Movement of the first and second objects is viewable through the transparent first and second chambers. A portion of the barrel between the first and second chambers is substantially non-transparent and blocks from view adjacent respective portions of the first and second chambers. When the first object moves downwardly through the fluid in the first chamber, the first object disappears behind the barrel non-transparent portion substantially at the same time as the second object appears from behind the barrel non-transparent portion as the second object moves downwardly through the fluid in the second chamber.
