Inspecting the exterior portion of a townhouse style condo recently, I noticed a few bright streamers attached to the corner of the building flapping in the early morning breeze. My first thought was, someone has left their Christmas decorations up a little long. As I walked around the exterior I noticed more of the same streamers attached to the building.
These bright and shiny streamers actually have a purpose. While they may appear to be a decoration, they have nothing to do with Christmas. They actually have a very specific purpose.
Can you guess what these streamers are doing?
