Once you knock dominoes over, you generally have to set them back up by hand. But in the case of this LEGO Technic machine by Grant Davis, the dominoes stand themselves back upright. Running in an infinite loop of 10 dominoes at a time, it can knock down and stand up dominoes at a rate of 120,000 per day.
