Bowed Pillars 7 feet 11.5 inches

Todays tower proved a good way not to make a tower. I made tall pillars 4x4 in cross section held together by "squares" 15.5 2x4 blocks wide on each edge and three layers thick. The pillars where each 122 layers. I only had three squares: at the top, middle, and floor. The tower stood 7 feet 11.5 inches tall. Not as tall as the previous one. The 122 layer tall pillars bowed like crazy. Clearly these pillars are too long without additional support. I should have used five or six squares for this height. No picture of this one (the bowed pillars were just too embarrassing). I guess I chaulk this one up to a learning experience.
