17. Cardboard Toy Garage and Car Ramp
For the little car enthusiast, a multi-level cardboard toy garage is the ultimate DIY project. Using a couple of sturdy boxes, you can construct parking decks connected by sweeping cardboard ramps. Draw parking bays, directional arrows, and helicopter landing pads on the decks using paint pens. You can even add a working elevator using a simple string-and-pulley system made from a cardboard cup and a wooden dowel. This project encourages spatial play and organization, as kids will love parking their toy cars in their designated spots at the end of the day.
