Testing MiniMax-H3 Physics: Fluid Replacement and Fire Effects in Video Generation

jaryP · reddit · 2026-08-30

The author tested the physics knowledge of the MiniMax-H3 model by using the H3-Ref model to replace water in a pouring video with sand, rocks, and a flammable black honey. The results showed realistic physical interactions for rocks tumbling over containers and honey blending with water, though the fire effect was unconvincing in the short clip. The author shared specific prompts and workflow settings used for the test.
