This is a video of LEGO lover and Youtuber Dr. Engine using a single Technic motor to drive increasingly longer LEGO chains, ending with a 3,000 link chain that I was surprised to even see move. Although, FULL DISCLOSURE: I am easy to surprise and often get jump scared if my girlfriend moves after she’s been sitting still next to me long enough. Just look at that chain go! Adding a section of black links so we can actually see the movement was a nice touch. Plus it reminded everyone over the age of 40 of playing Snake on their old Nokia 6110 brick phones. I still keep mine by the side of the bed in case an intruder breaks in.
