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
When it is deflated you have the least amount of surface area in the balloon to apply pressure to with your lungs.
As it inflates, it is creating MORE surface area but that SAME small entry point (from the nozzle) will require less applied pressure to stretch the entire balloon.
So a deflated balloon is the smallest surface area we can apply pressure to, which means the force required to inflate it would be the highest.
Heat also helps with elasticity (but not too much!!). This, combined with a little bit of “elastic memory” is why you can struggle to blow up a balloon, but once you get a lungful or two in, you can deflate it and do it again more easily.
