A reversible force measuring device that can comprise at least one cavity, at least one load receiving area, and at least one indicating material; wherein the indicating material moves in or out of the at least one cavity as its volume changes to indicate the magnitude and/or direction of the applied loads. A reversible force measuring device that can comprise at least one cavity, at least one load receiving area, and at least one indicating material; a fastener causes the indicating material to move in and out of the at least one cavity to indicate the magnitude and/or direction of the applied loads. A reversible force measuring device comprising at least two independent cavities, at least one load receiving area, and at least one indicating material; wherein the difference in volume changes indicates the force as the indicating material moves in or out of the at least two cavities.
