When we inflate a balloon, we are forcing air into the balloon. ... As we keep blowing, the air pressure builds up inside the balloon, and the rubber expands to its maximum limits. If we blow again, the balloon won't be able to expand but the air that we blows in need space still, and the balloon bursts.
