Balancing Scale / product design

The product is a balancing kitchen scale. This scale does not need springs nor mechanism. The base of the scale is an arc shape which will rock. The idea came from Chinese ancient scales. The top shows the container, a bead and measurements. When the container is empty, the scale is balanced, once there are things in the container, the scale will lean to container side, and then just pull the beads towards the other end until it is balanced; check the measurements next to the bead. Inside the Balancing Scale there is a weight attached to the bead, so the bead is actually heavier than it looks. This helps save the battery and it lasts forever.
