Fax machines used to baffle me. I figured the paper you fed into it was crumpled up and squeezed into that tiny cable, then it travelled about halfway to the destination. When it got there, the paper would flatten itself out again and somehow split into two papers, each one with only half the thickness of the original. One of these would travel inside the cable back to where it was sent, and the other would travel to the receiver, both inside those tiny cables. I was amazed that all this could take place within a few seconds, and that the papers showed no appearance of having been crumpled up.
