SEAWEED
What is interesting about seaweed is that the water around it affects the movement, causing it to move in a wavy motion . Seaweed is supple and strectchy which can reduce the drag to help it flow with the current.
ROAD SYSTEM
This road system was built to circle downwards to guide vehicles through an area. What I find interesting is that everything on this system has to travel in a spiral motion.
