What this shows

A floor pump with brass bezel pressure gauge (sidebar dial and 3D needle on the barrel), hose, and a glossy strawberry jelly Bot sphere (MeshPhysicalMaterial + RoomEnvironment like #41). Gold T-handle on a chrome rod stays attached while you pump. Slanted dark oval eyes under the gel progressively squish shut as pressure rises. Click, tap, or Space pumps air in; the skin stretches unevenly until it pops into flat fragments that scatter and settle. Water mode adds a fill and splash burst with the same fragment logic. Flick, reset, slow motion, pump count, and pressure readouts. Optional sound is synthesized in the page and stays off until you enable it.

How it was made

A self-contained WebGL demo in the iframe (three.js from a CDN). If WebGL is missing, the frame shows an explanation instead of an empty slot. There is no video on this page.
