We are in the same hemisphere, so Coriolis doesn't apply. Centrifugal force, gravity and AIR are the ruling forces. centrifigul force forces the first layer of paper away from the roll, air gets under it, and then there is no more contact friction. Gravity then pullls the paper to the ground, the kid keeps spinning the roll untill it's all on the ground.
You're more than welcome to go to your bathroom and try it :P
