Condition :   Good  
Principle :   Inertia of Mass   
Area of Study :  Mechanics  
Equipment :   Tissue Paper Roll, Support Stand.

Procedure :   Place the tissue paper roll on the support stand so that it rolls freely.  A gentle accelerating pull will unroll the tissue without breaking.  The roll may even continue unrolling for several seconds after you have stopped pulling.  

A quick jerk on the roll will do nothing but break the tissue without moving (unrolling) the roll.
