How do you get a balloon to blow up inside a glass flask? This demonstration uses the change of water into steam to expand and then reduce the volume of a rubber balloon. As the balloon gets smaller, atmospheric pressure forces the prairie dogging balloons into various sized containers.
Air particles are made up of matter and take up the space that it is in, it also presses on the surfaces that it contacts. This pushing force is called pressure. Air can be compressed! The particles move closer together and fill a smaller space.
Oxygen can be pushed into water so that it is absorbed under pressure - given room to expand, the oxygen comes back out of the water and into the air. Henry's Law explains gas absorption into water, which involves a bit of chemistry:
