Globular cluster (GC) streams, debris of stars tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass-loss rate. In this work, we employ a novel particle spray algorithm that can accurately reproduce the morphology of streams of various orbital types, enabling us to uncover the relationship between the GC mass-loss history and stream density profiles. Using recent discoveries of GC streams from Gaia Data Release 3, we present, for the first time, a catalog of directly observed mass-loss rates for 12 Galactic GCs, ranging from 0.5 to 200 M_⊙ Myr^–1. By fitting power-law relations between the mass-loss rate and key GC properties, we identify positive correlations with GC mass and orbital frequency, consistent with the predictions from N-body simulations.
