Begin at the supplied illustrated first frame. Fixed side camera and fixed lower pad. The upper pad moves slowly down a short distance, compressing the single yellow sponge so it becomes shorter and slightly wider while staying one connected piece. The dark pore marks stay on its surface. The upper pad then returns to its starting height and the sponge gently regains approximately its original outline. No crushing into fragments, liquid, replacement sponge or camera zoom. End after this one compression-and-release cycle and hold the recovered form.
