Imaging & Setup
The experiment was filmed using a Canon EOS R50 equipped with the RF-S 18–45 mm f/4.5–6.3 IS STM kit lens. Video was captured in Full HD (1080p) at 120 fps using the high-frame-rate slow-motion mode. Post-processing was performed in Adobe Spark, where contrast and timing were adjusted. Background music was added from the Adobe stock library and credited accordingly.
Physical Phenomena
The gel is a suspension of calcium carbonate in acetic acid (which can form soluble calcium salts and liberate CO₂), producing localized fuel pockets that burn unevenly. Incomplete combustion of the fuel produces incandescent soot (yellow-orange color), while heated gas rises under buoyancy, producing plumes and vortex-shedding that make the flame flicker.

This has very good focus. The edges of the flame are quite crisp and clear.
Permissioned opinion: I think it could be super interesting and fun if there were maybe a couple of petridishes next to each other and they would “dance” differntly and add a new layer of art to this work
