This is a very simple experiment in elementary forces. The environment is a zero-gravity atmosphere that applies a small drag force to moving objects. The environment is seeded with a number of particles that have a weak, long-range attractive force towards one another, and a strong, short-range repulsive force. The result is a mass of particles that clump together but do not physically connect to one another. This is analogous to how liquid water acts in zero-gravity.
With a more inventive bonding structure, we intend to use these basic attractive/repulsive forces to generate interesting and functional collections of particles.
