Study of an earth-worm crossing a sheet of paper.
On his first encounter of a dry sheet of paper the worm seemed disturbed, a big obstacle to overcome. He lifted is front part about an inch of the ground scouting for directions, it appeard as if he wanted to look into the distance to figure out if the trip across the big white blank was possible. The worm waited till the paper was wet enough before he started to move on. The whole process of orientation and crossing took about 40 minutes.
