Spiral

Begin with a flat-lying Bioblo block.

The following blocks are each placed slightly rotated (about 10°), whereby the amount of shifting (one could also say: the overhang) at both ends of the block should be equal, so that the spiral maintains a vertical central axis.

TIP: You can also use several Bioblos lying next to each other as starting point for the spiral. With a little practice you can create the most fascinating constructions!
