War Zone Obstacle #1

This in an obstacle that can be used in a K'NEX war or for anything else that you might use it for. You can use larger pieces like red or gray rods if you would like. I just had to use smaller ones to fit in the picture. WARNING: This is mostly for looks! This is really just used for showing a boundary or area for a bunker, base, etc. This is not supposed to be used for actually blocking something!
picture 1 is an example (mini)
picture 2 is them stacked (mini)
picture 3 is the real one (FULL SIZED)
I just made these to show the most piece efficient way to make war zone obstacles!
