So I playing a game of Jenga with my 3 year old. Which basically amounts to building tall towers and watching her knocking them down. And I got to thinking, these towers suck. The columns are too close together, they wobble, and the slightest bump brings them crashing down. So I got some rubber bands, and made some prestressed beams. I took three Jenga blocks end to end, and wrapped a rubber band around them length wise. Now my floors had three times as much rentable floor space, And everything seemed a whole lot more stable.
