For car-themed birthday party ideas, send out race car invitations, make road cone party hats, serve race car party food, make model cars for a party activity, and watch a car-themed movie. Send home small toy cars for the party favors.
To make a race car invitation, use the computer to make a VIP pass for each child to wear to the party. Use wording such as "start your engines and speed on over" to include the where and when of the party details. To make a road cone party hat, roll a cone of orange felt, glue it with a hot glue gun, and add a ribbon for a tie. For party food, cut a watermelon in the shape of a car, and fill it with fruit. Make sugar cookies in car shapes, and add round candies for wheels. Decorate a sheet cake like a race track with colored icing, and decorate with toy race cars.
For a fun party activity, decorate toilet paper tubes with acrylic paint and colored paper to make race cars. Cut out black craft foam circles for the wheels, and attach them using paper fasteners. Some car-themed movies that are appropriate for kids include "Cars," "Chitty Chitty Bang Bang," "The Great Race" and "The Love Bug."
