how do paper towels absorb water
Making the world better, one answer at a time. Paper Towels can absorb water in two different ways. First, microscopic spaces in the towel have space for water to soak in, like a sponge. The water stays trapped in the spaces until squeezed out. The second way is when a chemical cellulose, which makes paper towels strong, soaks up the water molecules. Most paper towels contain both microscopic spaces and cellulose, so it absorbs the water extra well.
