ABSTRACT:
A dietary control eating utensil is disclosed for indicating when food can be eaten therewith. The handle of the utensil includes a gravity-powered timing device. The device includes an elongated transparent material chamber for containing immiscible fluids having different densities such as air and mineral oil. The lighter density fluid forms a visible signal within the chamber that is moveable between the distal and proximal ends. The period associated with the movement of the visible signal depends on the different elevations of the chamber ends. The shape of the chamber along with the density of the two fluids also contributes to the time period the visible signal takes to move between the two ends of the chamber. When the air bubble moves to a predetermined position within the chamber, this indicates when the utensil may be used for consuming food.
