Hey Brain Stuff folks, does an EMP really fry all electronics permanently when it goes off, or is that just in the movies?

I experienced it in a plane but all plane are pressurized why it still happen.

It's strange, I am sure that I have had my ears pop before, but I can't recall a time or the sensation. Does it hurt? I think I would remember it if it was painful as I am such a wimp. Anyway, that was a great video.

That's why I hate when the plane is about to land... I can't hear anything :/

Is there any problem with that I am blowing air through my ear.

[fernandaveregue]

I really hate when it happens with my ears... My ears are very sensitive, they pop quickly when have this difference of pressure. I say that 'cause in a travel my ears pop while my friend's ears didn't pop so easily... I feel very uncomfortable.

And thats why everything gets complicated when you have serious congestion.

[hannah-fyfs]

When you equalize under water, does it hurt?

[ChiaraWatson]

Is the unequal pressure why my hearing capabilities go down before my ears pop?
