Official Cardboard Carnival Rules
Who can participate?
The Cardboard Carnival: Marble Adventure Edition is open to all D65 students and Evanston residents in grades 4th – 8th. Registration is required. Click the button below to register.
What materials can I use?
Your marble adventure must be made from cardboard, recycled materials, and/or other everyday materials. We ask that you don’t use tracks or materials specifically designed for marble runs. We will also provide a free kit to help you get started. The kit includes a hot glue gun, motors, craft sticks, duct tape, and more (you will need to return non-consumable materials back to the library). You can find the full kit contents list here:
What do I need to include in my marble adventure?
Your marble adventure must include a minimum of 5 original design elements from the following list. An original design element is something you designed and built yourself. It is okay to use some pre-built materials, but you need to use it in a way that the material was not originally designed to do, such as using a stack of books as a support tower.
Your marble adventure must also include a moving element powered by a motor. We will provide you with the motor control board and the motor in your Cardboard Carnival Kit. We will contact you about picking up your kit materials once you have registered for the challenge.
You can and are encouraged to include more design elements though. Some elements are critical to a marble adventure and others are optional. Feel free to mix and match elements. The more design elements you include the more prize tokens you can earn. We have tutorials you can watch for each design element below.

Where can I pick up my challenge kit?

Pick up locations include the Evanston Public Library, 3rd Floor Help Desk and the Robert Crown Library Branch. If you are not able to pick up your kit from the library, please use the Help Form below to contact us. We will figure out a way to get a kit to you.
When is my marble adventure due?
The challenge begins Saturday, January 23rd. You have six weeks to plan, design, construct and test your adventure, so take your time and work to create a cool marble adventure and earn as many prize tokens as possible. You must submit your final project before 8:00 pm on Monday, March 8, 2021.
