You can find large cardboard boxes for purchase at most home improvement stores. Try to hold onto any leftover cardboard boxes that you come across.
The short flap that you leave outside of the box will be back of the car.
The middle section will be where you’ll put the car’s doors.
By the end of this step, the back two-thirds the top should be separated from the sides of the box. Have an adult help you make the cuts with a box cutter.
Place the cardboard box on spread-out newspapers or a large sheet of cardboard so you don’t accidentally get paint on the floor. Give the paint an hour or so to dry before you move on to the next steps.
To make rims, you can cover strips of cardboard with duct tape and then glue them onto the wheels.
To make headlights, for example, you can cut small circles out of another piece of cardboard, paint them yellow, and then glue them onto the front of the car. Or you can use the bottom part of a paper cup. You can use small, rectangular cardboard strips covered in duct tape or ice pop sticks spray-painted silver to make a grill. Using different colored markers to add lights and other details is another option.
A good rule of thumb is to make the car’s height 1/3 its length. Be sure to draw half circles where the 2 wheel wells should be.
If you don’t have a box cutter, you can also try using a strong pair of scissors.
To accurately measure curved edges, use a string and then check the string’s length on a ruler. If the top of your car is curvy, you may need to use your fingers to bend the cardboard segment into shape.
Cut the tip off the skewer before you put it into the wheel.
Leave 1–2 centimetres (0. 39–0. 79 in) between this wheel and the plastic straw so that your wheels will be able to spin.
