# Menger Sponge

A Menger Sponge ist a fractal curve with a surface area approching $\infty$ while the volume approches $0$ for higher order Merger sponges.

This seemed interesting, so I built one out of paper.

1. Fold 72 sonobe:
2. Insert the individual sonobe together to form the merger sponge:

Next step: Build a $M_2$ merger sponge (left as an exercise for the reader).
