Mills' Mess objects, the pattern is adaptable to rings, clubs, torches and a variety of other juggling props. Four-, five-, and (recently) six- and seven-ball variations of these patterns have also been performed, as well as four, five and six clubs. Rubenstein's Revenge is a heavily embellished and distorted Mills Mess. It is one of the most famous Mills Mess variations. The Boston Mess is a variant of Mills Mess in which the arms similarly cross and uncross, but the balls are thrown in columns. It is performed with three balls in a columnar cascade pattern (siteswap 3). Cherry Picking is a
Collision cascade liquid flow of atoms, but if the projectile size above roughly 100,000 atoms, the crater production mechanism switches to the same mechanism as that of macroscopic craters produced by bullets or asteroids. The fact that lots of atoms are displaced by a cascade means that ions can be used to deliberately mix materials, even for materials that are normally thermodynamically immiscible. This effect is known as ion beam mixing. The non-equilibrium nature of irradiation can also be used to drive materials out of thermodynamic equilibrium, and thus form new kinds of alloys.
