Materials Per Child: a small sponge a clear plastic cup or container Key Questions Where does the water go? Activity Give each child a sponge. Ask them to make their sponge wet with the water in their container. Challenge them to soak up all the water with their sponge.

Once they soak up all the water with their sponge, can they get all the water out again? 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. This is why we have to dry ourselves with an absorbent towel after getting out of the shower. Were it not for water's sticky properties, we would we dry in seconds without toweling off.

Water sticks to nothing, however, as well as more water. Water molecules are highly attracted to one another. So when you place a wet sponge against a wet surface, the water will jump to bind with the water that is already in the sponge, increasing the sponge's soaking abilities.
