1F20.14 - Inertia of Rest - Tissue Paper Roll
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.
