Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with structures sized between 1 to 100 nanometre in at least one dimension, and involves developing materials or devices possessing at least one dimension within that size.

Bauxite is a dark-red sedimentary stone. Once highly prized as the only practical source of magma-safe mechanisms to create magma-proof devices, its importance has declined with the addition of many new heat-resistant forms of stone as well as the ability to make metal mechanisms from iron and steel.Nevertheless, it is still used by some long-time players for nostalgia and its rare, bloody
