Title: Equal — A Study in Pressure
Exact creative prompt: Create a calm industrial science exhibit about a water-filled U-tube. Use pale laboratory mint, teal liquid, symmetrical pressure and height gauges, a centered serif title, a finely ruled SVG apparatus and a broad bottom control dock. A signed pressure slider must calculate the hydrostatic height difference using water density 1000 kg/m³ and gravity 9.81 m/s², updating both liquid levels and numeric readouts. Include reset and a schematic-model disclosure. Self-contained responsive HTML5, inline CSS/JS, no dependencies.
Description: A visual hydrostatics instrument that makes an invisible pressure difference legible through connected liquid columns.
Major visual techniques: Inline SVG clipping; gradient liquid; technical grid; paired numerical gauges; centered laboratory composition; controlled mint/teal palette.
Intended interaction model: Apply positive or negative pressure with the slider, observe calculated level displacement and reset to equilibrium.
