Wet paper curls because the water causes the paper fibers to expand and contract unevenly as they absorb and release moisture. This uneven expansion and contraction creates internal stresses within the paper, causing it to warp and curl. Additionally, the water weakens the paper fibers, making them more susceptible to bending and curling. As the paper dries, the uneven distribution of moisture and the weakened fibers contribute to the curling effect. **
