OBBL Ideas
Pillars and Floating Balls



* The quarter-circle yellow arch blocks can support a yellow horizontal beam. Build your supporting pillars and place the quarter-circles on them. Near the top of the white grid, piece together a yellow beam and let it fall until its ends touch the quarter-circle arches. The beam should become "glued" to the yellow quarter-circles. What is the longest yellow beam that you can support?

* Blue balls can appear to float when you put them together with large quarter-circles or smaller half-circles.
