Forces on a constrained party balloon
Hi, A party balloon is glued onto an straw. The user inflates the balloon by blowing through the straw. However, the balloon is constrained due the presence of a rigid wall just beyond it (causing the balloon to expand upwards or backwards towards the person inflating it!). I would like to know if it is possible to estimate the forces between the balloon and the straw (at the point of gluing).
Strange question, I know.

I'd start by knowing the PSI. then I would find the area of the bonded contact surface in square inches.
Then I would divide PSI by square inches to get pounds. That number in pounds would be the force.
Just a guess.
