    An inflated tyre is firm because of the ‘push’ of the air particles against the inner tyre wall.

    When we drink from a plastic bottle and prevent the air moving in to fill the space of the lost liquid, the air outside the bottle has more ‘push’ than what is inside the bottle. As a result, the bottle collapses.

    Wind is what we feel when the air particles move and flow around us.
