When I built our ball wall / marble run, my goal was to have a flexible design so the pieces could also be used for water play and for a sensory table. With this week’s nice weather, we were able to test the theory, and it was a great success in terms of fun!
You can see there is some leaking that happens around the joints when two same-dimension connectors or pipes are next to each other (which was fine with my son – he liked that there was water coming out everywhere), but probably 50 – 60% of the volume of the water made it all the way through the maze.
The end point of our water maze was a plastic cup with two magnets glued on it. Whenever it filled up, we replaced it with the other cup, and poured the captured water back through the maze – we also had a tub full of water nearby.
The best part: when the cup fills up all the way with water, the weight is more than the magnets can support, so it slides to the ground. “Level complete!”
