We anticipated vertical agitation to gener-ate both an active force and torque on these particles and converged on this specific design after systematically excluding out other de-signs based on the nature of active dynamics observed (see fig. S4). Our Janus ellipsoids had a major axis, = 6 mm, and minor axes, = 3 mm and = 2.1 mm.

Here, we try to address this question with a wet granu-lar model system. Granular matter, besides its ubiquity in nature[18, 19], has been frequently used as a model system for phase transitions far from thermal equilibrium [20 29], due to the strongly dissipative particle-particle interactions. Here, we use a mono-layer of wet particles

Granular formulations are made by placing the active ingredi-ent on a core material such as clay, sand or ground corncob. The core material imparts various qualities (e.g. flowability, dust, release rates) to the formulation. These granular formulations are applied as pur-chased, i.e. dry. In contrast, water dispersible granules have a granular
