  In recent years the understanding on the limits of the smallest possible
droplet of the Quark Gluon Plasma has been called into question. Experimental
results from both the Large Hadron Collider and the Relativistic Heavy Ion
Collider have provided hints that the Quark Gluon Plasma may be produced in
systems as small as that formed in pPb or dAu collisions. Yet alternative
explanations still exist from correlations arising from quarks and gluons in a
color glass condensate picture. In order to resolve these two scenarios, a
system size scan has been proposed at the Large Hadron Collider for collisions
of ArAr and OO. Here we make predictions for a possible future run of ArAr and
OO collisions at the Large Hadron Collider and study the system size dependence
of a variety of flow observables. We find that linear response (from the
initial conditions to the final flow harmonics) becomes more dominant in
smaller systems whereas linear+cubic response can accurately predict
multi-particle cumulants for a wide range of centralities in large systems.
