Click the green flag. When prompted, answer the question. Later in the project, control the simulation with left and right arrow keys. (If you do not follow the directions for the simulation part, it is possible for the project to force quit.)
Today, while hiking along the Erie Canal, I watched Lock 32 empty out. Water is powerful. The mechanics of moving so much water is interesting.The hinges on the gates are huge! My curiosity led me to wonder about how locks work. Thank you to @Juf-Pinky from the Netherlands who taught me the technique I used to render the big brown canal lock.
