Can Water Solve a Maze?

Science YouTuber Steve Mould is becoming well-known for making physics videos with specially-constructed cross-section demonstrations, i.e. 2D hydrodynamic mechanisms. And so when his online audience began sending him @bergmanjoe’s digital simulation of liquid filling a maze, he decided to build it to see what would really happen.

“I actually made four mazes in total,” Mould explains, “a simpler one and a more complex one, and I also made large versions of those two mazes.”
