What can we use instead of wooden skewers, bottle caps, or a drinking straw if we can't find them?

If wooden skewers or bottle caps are hard to find, use straight pencils or thin dowels as axles and large buttons, small jar lids, or toy wheels as replacements for the bottle cap wheels, and use a firm paper tube or rolled cardboard in place of the drinking straw while following steps 2–6 and 9–10 to assemble them.

My car doesn't roll or the wheels wobble—what should I check first?

If the wheels rub or the car won't roll straight, check that the axle holes (step 2) aren't too tight, move the tape stop on the wheel or widen the holes slightly and trim any skewer ends flush as in steps 6–7 to reduce friction and wobble.

How can I adapt this project for younger or older kids?

For preschoolers have an adult pre-cut the cardboard and make the axle holes then let the child push on wheels and tape them (steps 1–6), while older kids can experiment with different sail shapes, axle placement, or glide surfaces (steps 8–11) to test speed and steering.

How can we make the wind-powered car more fun or go better after the basic build?

To enhance performance and personalization, decorate the cardboard body, try different sail sizes or angles on the straw mast (steps 9–11), add small tape weights near the front or back to change balance, or make a tiny rudder to improve straight-line rolling.
