When you squeeze a balloon you re putting all of the air to the top or the bottom of the balloon so at some point it will overflow of so much air that it will pop. It is kind of like when we hold our breath for to long, instead of popping, we pass out. Because we need air and so does the balloon. If the balloon was meant to be squeezed, it would've been all mushy so you can squeeze it and it would be like goo. So if you don't wanna pop your balloon, then don't squeeze it.
