ASMR-Glowing lava cube

Macro-shot ASMR video: a glowing lava cube wrapped in a dark, hardened basalt crust rests on a scorched stone slab. A razor-sharp stainless-steel knife slowly pierces and slices through the brittle shell; as the blade breaks the crust, incandescent lava gushes out and spreads, bubbling and sizzling against the cool surface. Ultra-slow-motion (4 s) in 4 K, cinematic rim lighting, rich shadows, shallow depth of field, crisp sizzling and crackling audio, no text or logos.
