1. What will happen to the paper towel inside the glass when it will be submerged upside down
in the basin of water?

As I observed even though you can’t see it, air is made up of matter. Because air is made of
matter it has mass and volume. Because air has volume it takes up space. This experiment
shows the air’s volume. The water is being absorbed, or soaked up, by the paper towel material
through a process called capillary action. Capillary action, also known as capillarity, is the rising
or absorption of liquids through small gaps and holes certain materials.

2. Will the paper towel inside the glass stay dry for long time? Why?

When the glass is lowered in the water, air is trapped inside of the glass because of the water
pushing up from below. Air is less dense than water so it is able to stay on top of the water. The
paper towel will not get wet as long as the air stays in the glass. Paper towels absorb water
when the water fills up into tiny air pockets in the paper towel. Once you get one part of the
paper towel wet it absorb into the rest of the paper towel in approximently 50 seconds or less
