[MCU] If pym particles were used to expand a solid steel ball within a hollow steel sphere of equal composition and strength, what would happen?

The main question being...do pym particles being used give the ball the ability to destroy the sphere on expansion, or would the equal strength cause them to reach some sort of equilibrious state where the size change would halt or they would forcibly weld together somehow?

Obviously, if the outer sphere was weaker, it would be destroyed, buy, what if the outer sphere was stronger?

What if there was a hole in the stronger outer sphere? Would the ball extrude through the hole?

Pym Particles are more magic than science.  They might blow up the outer sphere, or they might leak-out into the outer sphere and make that expand too.  Hank may know, but he doesn't seem too keen to reveal his secrets.
