While strolling through the Baraha at 3am in the morning, I came across the pin ball machine. I gave it a couple tries and noticed that the LEDs lit up when the ball collided with certain areas in the apparatus.
Building on that concept, I created a simple maze that began in the top left corner and ended in the bottom right. When the ball (a ping pong ball wrapped in aluminum foil) reached the end of the maze, it will bridge together the two pieces of aluminum foil that are connected to the LED circuit.
It took me a few tries to get the end-of-maze foil dimensions/placement correct as the surface area in which the ball is actually in contact with the surface is quite small. The ball had to be right in the middle of the two pieces of foil in order for the circuit to be complete.
The following is a demonstration of the maze in action:
