Generate a video of a bag falling from above in a slow, graceful motion. As the first bag lands, it squashes and deforms slightly, creating a bouncy, sponge-like effect before returning to its original shape. Immediately afterward, a second bag falls from above, landing directly on top of the first bag, creating the same soft, squishy effect. The background is white, with soft lighting that emphasizes each bag's texture and color, adding to the playful, sponge-like aesthetic.
