I mean your average party balloon, when it’s completely deflated, it seems you have to put extra effort into getting it going. As soon as it starts inflating, you need less effort.
In: Physics
If the deflated balloon has one square inch of surface area and you put one pound per square inch (psi) into it, there is one pound of force trying to stretch the balloon. If the balloon has 10 square inches of surface area and you put one psi into it, there are 10 pounds of force stretching the balloon.
