I understand the hypothetical situation being described in the first post, so no need to debate perfect glass or whatever.
Even with an explosion creating equal forces in every direction, so that no one force is stronger than another, the explosion itself is already big enough to create a force strong enough to overpower your "sphere" and it will shatter and expand, along with all the material and gas released by your hypothetical bomb.
Enjoy!
