Bringing the Kelvin problem solutions to life with the first-ever polymeric Weaire-Phelan structures

An interesting class of problems in geometry concerns tiling or tessellation, in which a surface or three-dimensional space is covered using one or more geometric shapes with no overlaps or gaps in between. One such tessellation problem is the "Kelvin problem," named after Lord Kelvin who solved it, which concerns the "tessellation of space into cells of equal volume with the least surface area."
