Water molecules are highly attracted to one another. Water sticks to nothing, however, as well as more water. Were it not for water's sticky properties, we would we dry in seconds without toweling off. This is why we have to dry ourselves with an absorbent towel after getting out of the shower. We don't think of it in this way, because it's not sticky like honey or glue, but it tends to stay on a surface. It should be noted that water itself is very sticky. You may have observed this phenomenon at work and wondered how it could be. Why a Wet Sponge Works BetterÄue to the properties of water itself, a wet sponge is often more effective at retaining water than a dry one. If you were to remove all of the empty space in a sponge, you would see that the actual matter inside this product would take up less than 1/3 of the sponge's actual size. Instead, the water is trapped inside until the sponge is forcibly squeezed. This prevents the water from sloshing right back out of the sponge. The holes between the fibers soak up the water and cause the fibrous material itself to swell. It is because of this empty space that the sponge can work so well. Loose fibers in the sponge create a product that is more empty space than anything else. The makeup of the sponge makes it is so effective at soaking up water and other liquids.
