The internet is enabling the democratization of real life hacks. In other words, people are using the net to share how to hack just about everything. In this case, we see a hack to control an elevator.
In a hurry or just don't like to stop at every floor while in an elevator? The guy in this video shows how to go straight to your floor with no stops. Hold the "close door" button and the "floor" button at the same time for about 4 seconds. I guess most elevators have this capability built in for emergencies and such.
