One bucket of corn. One volcano.

Vertical 9:16, 15 seconds, one continuous handheld smartphone shot, no cuts, realistic iPhone footage. Start exactly on @image1. The person is the same person as @image2 (your photo): same face, hair and outfit throughout.

0-1s: They sit in the open helicopter door holding the steel bucket of dry corn kernels and look down at it, calm and focused. Slight handheld shake.
1-3s: They tip the bucket out the open door to the left. A thick golden stream of kernels pours out and falls. Camera drifts left and down to follow the stream.
3-5s: Camera tilts down past the door sill to look straight down. The stream of kernels arcs down into a round glowing orange-red lava crater directly below. The person leaves the frame. Only their hand and the tilted bucket stay at the edge of frame, then leave.
5-8s: Camera holds looking down on the crater. The metal door sill runs diagonally across the bottom corner. The last kernels disappear into the bubbling lava as grey smoke drifts past. Tiny white specks of popped popcorn start appearing in the center of the lava.
8-11s: The popcorn multiplies quickly until a fluffy white mound covers the whole crater. The red glow shows only around the rim.
11-12.5s: The mound swells past the rim and grows toward the camera. The first popped kernels launch upward.
12.5-15s: Popcorn erupts straight up at the helicopter. Large out-of-focus pieces fly past the lens. The camera swings back into the cabin, catching the door frame and the person's legs, as popcorn floods the doorway. The final frame is completely filled with popcorn.

Audio: loud helicopter rotor and wind noise throughout, a hiss as the kernels hit the lava, then rapid popping that builds to a roar during the eruption. No music, no speech.
