A glass bottle dropped out of a plane over the kalahari was magic in "The gods must be crazy".
A magic thing, that looked like water but was hard as rock, smooth, hollow, so many strange qualities.
It drove the tribesmen mad, until they ordered the man who originally found it to carry it away and dispose of it back to the gods who had sent it down as a curse.
Technology as freakish thing of unreality for the most mundane of modern things, a bottle. Similar strangeness can be seen in real life, where some native tribesmen literally couldn't see the European ships moored offshore as boats, things made of human hands. . .instead they were strange looking islands or piles of flotsam. . .they were so beyond comprehension as to be impossible to be seen for what they were.
If your culture casually uses fire rods, I suspect you'd use one casually without batting an eye. . .if you'd never seen one before, likely it's as dangerous to your safety and sanity as a Zippo handed to paleolithic man.
In our world, overt magic ala "Fireball" is fantasy, so believing in it is insane, but in any magic using fantasy world the magic is real, and thus part of reality, so it's sane to believe in it. It is only madness if as the world designer you decide, "and even if magic is real, it's still unreal, and makes you mad." (Heck, I feel that way about a lot of quantum physics in the real world, it's only rational if you're a little crazy).
