Why is Iodine Attracted to Paper?

Question

For my Human Physiology/Lab Honors class, we performed an experiment in which iodine was placed on the hands and the arms and covered by a piece of paper for thirty-five minutes. Following this time, my partner and I discovered that the iodine on her palms had collected onto the sheet of paper covering it, but that the iodine on her arms had not stained the piece of paper covering it. We believe that the dermal papillae located on the palms may have caused the iodine to collect in her palms more than on her arms, but what in the composition of paper would have caused the iodine to be attracted to the paper?

Answer 1

Isnt that a little farfetched?
I think the explanation is simpler. Palms do not have as many pores as arms,Neither is it hairy. Ergo, liquid ( if you used an iodine solution ) will pool within the palm into droplets which will be attracted to paper.

On the other hand , the iodine on the arms settle into a wider surface consisting of skin, pores and hair follicles. They cease to be as round.

And the attraction to paper? It is more porous than skin.
