The pressure inside a football is caused by the air particles inside the ball being compressed by the addition of increasing amounts of air. The standard PSI of a professional football is 13 psi (Pounds per square inch).
Gas is made up of lots of particles that are all flying about bouncing of anything the touch. The more pressure there is the moreparticles there. So at normal pressure outside the ball there is a normal amount of particles hitting of the outside of the ball. On the inside of the ball the pressure is higher so there are lots of particles hitting of the hinside of the ball effectively pushing it out. Hope this makes sense :)

more gas particles increases the pressure inside the balloon expanding it, since gas particles hit the inside of the balloon.
