Found a bug where blobs were getting stuck hovering mid-glass since the liquid crossed the buoyancy threshold partway up. I'm lowering the ambient liquid temperature so blobs only rise after heating at the bottom and sink after cooling at the top.

The blobs are still detaching too early and hovering low instead of rising properly, so I'll make the wax stay in the bottom pool longer to heat up before releasing, giving each blob enough momentum to reach the top.

Temperatures are converging to ~0.5 because touching blobs average heat and velocity too aggressively. I'm weakening that coupling and removing the cohesion pull.

I've identified that merges between hot rising and cold sinking blobs cause them to stall mid-glass. I'll restrict merging to blobs moving in similar directions and cool the ambient liquid slightly to fix this.

Bottom congestion: blobs piled on top of each other never touch the heated glass, so they stay lukewarm. I'm switching to a heat field that falls off with height, so the whole lower pile warms up.

That approach backfired—smooth height-varying heating just creates a stable hover point. I'll fix it with proper hysteresis instead: a distinct hot zone at the bottom that holds the wax until it melts, with cooling only applied above it.

I can't render a screenshot since headless Chrome is blocked by the sandbox, so I reviewed the shader manually and found a real bug: `pow()` used with a negative base in the glass highlight, which is undefined in GLSL. I'll fix that along with a few small cleanups.

I've built the lava lamp as `index.html`, but I haven't seen it running. The sandbox blocked headless Chrome, so there's no screenshot, and neither the look nor the 60 fps target has been checked in a real browser. To see it, run `open index.html`.
**What's in it**
- **Scene:** a wall and a wooden desk drawn with CSS. The lamp has a metal base, a tapered glass body and a domed cap. When it's on, warm light falls on the wall and desk; when it's off, the room goes dark.
- **Wax:** blobs heat up in a molten pool at the bottom and rise once they're hot. They cool under the cap and then sink. Touching blobs flow together visually, and they really merge (keeping the same total amount of wax) when they meet while moving the same way. Large moving blobs split in two, and the pieces pull apart. Blobs stretch as they move and are lit from below.
- **Switch:** a toggle on the lamp's cord, on the desk. Tapping the lamp itself also toggles it. The light fades in and out. With the lamp off, the wax slowly sinks and settles into a few lumps at the bottom. Switch it back on and they heat up and start rising again. The page opens with the lamp already running.
- **No external requests:** there are no fonts or scripts from elsewhere, and the favicon is inlined so the browser doesn't fetch `/favicon.ico`.
- **Phone fit:** the lamp sizes itself to the screen in portrait or landscape, and the switch has a large touch area.
- **60 fps:** the lamp is drawn in a single WebGL pass, with pixel density capped at 2×. If frames drop below about 50 fps, it renders at a lower resolution (down to half).
**What I tested**
I ran the wax physics on its own in JavaScriptCore, since Node won't start in this sandbox. The first versions stalled: blobs hovered mid-glass. Blobs now only heat in the bottom pool and stay there until hot, and wait under the cap until cold. After that fix:
- Over 5 simulated minutes, blobs reached the top 31 times, with 4 to 9 blobs at any moment as they merged and split.
- Switching off sank everything into 2–3 lumps; switching back on got the wax moving again.
I also checked that the script parses and fixed an invalid `pow()` call in the shader.
If WebGL isn't available, the page shows a message instead of the lamp.

I've built the lava lamp as `index.html`, but I haven't seen it running. The sandbox blocked headless Chrome, so there's no screenshot, and neither the look nor the 60 fps target has been checked in a real browser. To see it, run `open index.html`.
**What's in it**
- **Scene:** a wall and a wooden desk drawn with CSS. The lamp has a metal base, a tapered glass body and a domed cap. When it's on, warm light falls on the wall and desk; when it's off, the room goes dark.
- **Wax:** blobs heat up in a molten pool at the bottom and rise once they're hot. They cool under the cap and then sink. Touching blobs flow together visually, and they really merge (keeping the same total amount of wax) when they meet while moving the same way. Large moving blobs split in two, and the pieces pull apart. Blobs stretch as they move and are lit from below.
- **Switch:** a toggle on the lamp's cord, on the desk. Tapping the lamp itself also toggles it. The light fades in and out. With the lamp off, the wax slowly sinks and settles into a few lumps at the bottom. Switch it back on and they heat up and start rising again. The page opens with the lamp already running.
- **No external requests:** there are no fonts or scripts from elsewhere, and the favicon is inlined so the browser doesn't fetch `/favicon.ico`.
- **Phone fit:** the lamp sizes itself to the screen in portrait or landscape, and the switch has a large touch area.
- **60 fps:** the lamp is drawn in a single WebGL pass, with pixel density capped at 2×. If frames drop below about 50 fps, it renders at a lower resolution (down to half).
**What I tested**
I ran the wax physics on its own in JavaScriptCore, since Node won't start in this sandbox. The first versions stalled: blobs hovered mid-glass. Blobs now only heat in the bottom pool and stay there until hot, and wait under the cap until cold. After that fix:
- Over 5 simulated minutes, blobs reached the top 31 times, with 4 to 9 blobs at any moment as they merged and split.
- Switching off sank everything into 2–3 lumps; switching back on got the wax moving again.
I also checked that the script parses and fixed an invalid `pow()` call in the shader.
If WebGL isn't available, the page shows a message instead of the lamp.
