Who this list is for
This is for a 12-year-old building a hand-controlled tabletop maze game with a ping-pong ball. The larger ball is used instead of a small marble for easier handling.
How to use this list
Use the shallow cardboard box lid as the maze tray. Sketch a route with ruler and pencil, then cut or arrange stiff corrugated cardboard and 20 jumbo wooden craft sticks as maze walls. Secure walls with strong craft glue and masking tape while they set. Use wooden dowels, cotton string, and round-head paper fasteners to create the hand-controlled movement system, then test the route with the ping-pong ball.
Common mistakes
Do not swap in a small marble; this design is intended for the ping-pong ball. Leave enough space between maze walls for the ball to roll without getting permanently stuck. Test the moving parts before adding extra tape or glue, since a tight string or misplaced fastener can limit control.
What is on this list
The list includes one shallow cardboard box lid, two corrugated cardboard sheets, 20 jumbo craft sticks, two wooden dowels, two meters of cotton string, eight round-head paper fasteners, one ping-pong ball, masking tape, strong craft glue, ruler, and pencil. Cross off materials you already have.
When you are done
Roll the ping-pong ball through the whole route and adjust any walls that block it. Let glued sections dry fully, then keep the tabletop labyrinth on a flat surface for play.
