Firework Shell Trajectory & Burst

A side-view 2D model of the same real ballistic and burst physics as the full 3D version: a firework shell climbs under launch velocity, gravity and quadratic air drag to its burst point, then detonates into stars that disperse in the vertical plane at a real burst velocity before falling and drifting under the same gravity-and-drag integration. Adjust launch angle, velocity, fuse delay, air drag and wind, or click in the sky to aim and fire toward any point; drag to pan and scroll to zoom the view.
