Answer:
During transportation, the glass wares may break
if they collide with each in the event of jerks. When they are wrapped in
straw, the force of jerk is transmitted to them through the pieces of straw in
a longer period of time.
Thus, the change in
momentum of the glass wares takes place in a longer period of time. Therefore,
a very small force is experienced by them in the event to jerks and hence they
do not break.
