Who this list is for

Older children age eight and up can build and test this cardboard marble run with an adult. The adult should cut cardboard and supervise the 20 marbles whenever younger siblings are nearby.

How to use this list

Cover the table with the protector sheet and sketch a route on large corrugated cardboard sheets with pencils and the metal ruler. An adult uses the utility knife to make needed cuts. Children can shape cardboard tubes, paper cups, and wooden craft sticks into ramps, channels, supports, and a finish area. Secure sections with masking tape and white glue, then aim the run into the small plastic catch tray. Use washable markers and sticker dots to mark start points or route choices.

Do not leave marbles on the floor or let younger children handle them unsupervised. Skip steep, unsupported ramps that will collapse when a marble rolls through. Avoid cutting cardboard with child-safe scissors when an adult utility knife is required for thick sections. Test one section at a time instead of gluing the full design before it works.

What is on this list

Gather four cardboard sheets, eight cardboard tubes, 12 paper cups, 100 craft sticks, two rolls of masking tape, white glue, two pairs of scissors, an adult utility knife, metal ruler, two pencils, 20 marbles, catch tray, markers, sticker dots, and a table protector. Cross off owned items.

When you are done

Collect every marble into the catch tray, let glued sections dry flat, and store reusable pieces together. Recycle scraps only after checking that no small marbles or useful parts are mixed in.
