We build a maze using playdoh. The object of the game is too get trough the maze without making anything buzz. Like the game Operation.
Build Maze with playdoh, having the inside all connect to the outside walls of the maze
Build circuit with power, makey makey and buzzer.
Two grounds are needed as the maze needs a start and an exit - thus two seperate walls
Mount your circuit close to your maze and tape it to the table
Plug alligator clip to one the the earth and into the outside wall.
Plug other alligator clip to the other earth and into the other outside wall.
Plug alligator clip into either left, right or space, you can use another conductor to the alligator clip like a carrot or just use the clip itself.
Try going trough the maze from start to finish without making it buzz
