What are three things that absorb water?

Water-Absorbing Materials You Can Find Around the House

Water absorption is a fascinating process driven by capillary action and the porous nature of certain substances. When liquid comes into contact with these materials, tiny spaces between their fibers draw the moisture inward, trapping it securely inside.

If you need to soak up a spill or understand how everyday items interact with liquids, several common objects do the job remarkably well. A sponge is perhaps the most iconic example, featuring a dense network of interconnected air pockets that hold large volumes of liquid relative to its size.

Paper-based products also excel at this task. Both a standard paper towel and ordinary paper are made from cellulose fibers that readily pull water molecules along microscopic channels. This same principle applies to textiles like a cotton face cloth or a soft sock, which use woven threads to capture and retain moisture efficiently.
