Materials needed:
First, we prepared all the necessary materials.
Then we drilled two holes opposite each other with a screwdriver.
We put a stick for skewers through the holes.
We added one cap to each end of the stick.
After putting the caps on each side, we checked the balance of our toy car.
We repeat the process and we drilled the holes on both sides and put one cap on each side.
We also checked the balance of our toy car again.
