Bubbling Potion

A magic potion fizzes — bubbles rise and pop at the surface.

The rule that makes it move

This is the whole thing. Phluxel runs it on every cell, every step — the animation is what happens when you repeat it.

PARAM _rate = 1; LET _q = BASE.R > 179 & BASE.G < 90 & BASE.B > 119; _q & S.R > 249 & S.G > 249 ? [255, 255, 255, 255] : (R > 249 & G > 249 & B > 249 ? [BASE] : (_q & RN < _rate ? [255, 255, 255, 255]))

Paste it into the Rule Editor, or pick Rising Bubbles (in liquid, BASE) from the template list and skip the typing.

Make it yourself

1. Open Phluxel and start a new field, or click Bubbling Potion in the starter gallery to get this exact setup.
2. Leave Wrap edges off — this one is meant to have real borders.
3. Press play. Change colours or numbers while it runs; you never have to stop and restart.
4. Export a seamless loop as GIF, APNG, MP4, a PNG sequence, or a sprite sheet.
