Look how tall it is!
Made a 24 foot tall tower and stuck it next to the main structure. This is only temporary, I just wanted to see what a really tall K'nex structure would look like. The tower is actually made of 3 replacement columns (part of the blue connector reclamation). Balls are definitely gonna hurt a lot falling from that high. My bigger concern is how are we going to unjam ball contraptions that far up?
