Watch a canal lock work one boat through

“Slow, and you'll wonder if anything's happening. Then a boat drops the height of a room in front of you and it makes sense.”

The Recipe

  1. Walk to the nearest lock on a canal or river, the one you cross without ever stopping.
  2. Wait for a boat and watch the whole cycle: the gates, the paddles opening, the water finding its level, the boat rising or sinking to meet the next stretch.
  3. If nothing comes in twenty minutes, read the lock cold instead: stand at the low gates, look up at the water held back above your head, and work out the order it all has to happen in.
