To make the invisible visible
As we can see in this photograph, there is a specific time when the sunlight gets tricky, and some cables, pipes, and metal rods can become almost invisible. Frequently, we fail to see them and end up hurt.
These people went camping and set up a canvas cover on their minivan. To hold it still, they need two metal rods. Wasn’t it wise to make them super visible, covering them with red noodles? No way will they miss them.
