The Magic Room

I push a button. Doors slide open. I step inside and the doors close. I push a button and the rooms shakes and makes noise for awhile. The doors open and I am somewhere else. Magic! Right?

But if I look closer I will notice that there is a gap in the floor between the hallway and the room. I might also notice that there are two sets of doors - one on the outside and one on the inside. I might also go up the stairs and see if the next floor above is the same as the one the doors open on when I push that button. Once I noticed that these "magic" rooms were called elevators I could look them up online or in an encyclopedia and see that they are large metal boxes suspended from cables that lift them up and lower by means of a large electric motor. Amazing engineering that saves me the trouble of climbing many floors worth of stairs, but "magic"? Not in the least.
