Triboluminescent Candy Glow — Crystal Fracture Discharge

Wintergreen candy glows when bitten because fracturing its non-centrosymmetric sucrose crystals separates charge across the new crack faces; once the resulting field crosses air's dielectric-breakdown threshold, a real electrostatic discharge ionizes the surrounding gas in a flash. This simulator renders the crystal in 3D cross-section, drives fracture and charge separation from a compressive force you apply by dragging or clicking, and shows the discharge only once the accumulated field genuinely crosses breakdown — not on a timer.
