“Science doesn’t tell us why the Big Bang happened, how the singularity occurred in the first place, or why it exploded when it did. It tells us there is objective scientific evidence that it occurred. So, what exactly was the Big Bang?” – Book III The Enigmatic Mystery

The Magdeburg Hemisphere experiment, conducted by Otto von Guericke in 1654, demonstrated the power of atmospheric pressure. Two large copper hemispheres were joined together, and air was evacuated from inside. The hemispheres were then unable to be separated due to the difference in pressure between the inside and outside, showing the strength of atmospheric pressure. The experiment is often considered a key demonstration of the vacuum and a precursor to modern studies of pressure and vacuums.

So, what is the diameter, like 3" or 4" 1 atmosphere is roughly 14.5psi? So 4"*π*14.5psi is 182lb at best but probably 20~30 lb less.

You could just calculate max based on 14 psi being exerted over the surface area of the sphere. Max vacuum pressure is 14psi.
