I've only had this happen when I did something kind of dumb like trying to use one on an airplane or walking outside in freezing weather with one in my pocket.

And you can react to that by saying "these things are crazy" or you can say "oh yeah, it's nothing but water, that makes sense."

There's still the occasional "too muck ink in the nib dripped into the cap" but that's hardly an explosion.
