What happens to a sponge when pressed?

When a sponge is pressed, it compresses and expels the water or liquid it has absorbed. The sponge's porous structure allows it to collapse under pressure, forcing the liquid out through its openings. Once the pressure is released, the sponge returns to its original shape, reabsorbing water as it expands back to its full volume. This ability to compress and expand is what makes sponges effective for cleaning and absorbing liquids.
