How to make a cube fall from the edge when part of it is outside in Unity

Question

Let's assume I have a 1x2x1 cube and it is balanced over an edge, since the weight of the cube is distributed perfectly, it doesn't fall, how to make it fall when part of the cube is over the edge?

I have tried adding invisible objects to both ends of the cube and then adding another invisible object on the edge so when they collide I change the center of mass of the cube, this seems to work but I think it is overly complex since I have to add that invisible object around all edges of my scene.

for falling or everything dependent to physics you need to add rigidBody to it. rigidBody has a property name CenterOfMass. its a vector3 property. you need to position it far from that edge to put force on outer side of that edge.
