mass of rigidbody

i have this wall of cubes, like a hundred of them, and their rigidbody mass is all 1. I want to make it all 0.01. Is there a way to do that?

Make them all children of an empty game object and attach this script to the parent(empty gamobject).

@script ExecuteInEditMode()

var mass:float; //in inspector change this to 0.01 or whatever you want.

function Update(){
 for(var child:Transform in transform){
  child.gameObject.rigidbody.mass = mass;
 }
}

the moment you type in a new mass value it should automatically change all.
