The sneaker that's a cake
A hand picks up the chef's knife and slowly slices straight down through the middle of the sneaker. The two halves fall apart to reveal it was a cake all along: soft sponge layers and white frosting inside, crumbs on the board. Locked-off close-up, soft daylight, the crunch of the knife and a soft thud as the halves fall.
Result: Starts right on the sneaker, slices straight through and lands almost exactly on the planned end frame.
Slip: The knife comes back out of the cake without leaving a cut or a mark.
