🎆 Fireworks Physics: Shell Ballistics, Burst Radius, Spark Drag and Emission Colours

A 3D night-harbour fireworks lab: shell ballistics with quadratic drag, fuse timing versus apogee, shape-mapped star bursts with drag-limited radius, emission-line colours and the flash-to-bang sound delay. Unlike the existing 2D fireworks toys it is a Blender-built 3D observer scene with measured-versus-analytic experiments.

⚙ Under the hood

A 3D night-harbour show seen from a virtual observer: shell ballistics with quadratic drag, fuse time versus apogee, shape-mapped star bursts (peony, ring, willow, palm, heart, split) with drag-limited radius, emission-line colours of named metals and the flash-to-bang sound delay. Unlike the existing 2D fireworks toys it is a Blender-built 3D scene with a show builder and in-page measured-versus-analytic checks.
