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
Imagine 2 circles made of string. One is larger than the other. When you cut the strings as expected the larger circle is made of a longer string. Now when you inflate the balloon you are applying a constant force along the entire length of that string. So if you had a string that is 6 inches and you put one pound of force per inch you are at 6 lbs of force. Well that force causes the circumference to increase meaning your string is getting longer. Now you continue to add air at 1 pound per inch only now your string is 8 inches long. That means over the entire length of the string you are now applying 8lbs of force instead of six. The problem is now it takes more air to stretch the balloon because of this increase in volume. But luckily it has become easier so as long as you have time you can Basically make the balloon as big as the material will allow.
