Things You'll Need

Instructions

1

Park your car in the exact spot you want to use as your perfect parking spot.
2

Set up the ladder on the driver's side of the car near the point where the windshield meets the hood.
3

Climb the ladder with the string and eyehook. Attach the eyehook to the ceiling or into a joist above the windshield of the car. Try to make it so the string, when it comes down, touches the windshield directly in front of the driver's eye level.
4

Tie the string to the eyehook and cut the end of the string so it touches the windshield.
5

Poke a hole in the tennis ball with the screwdriver.
6

Tie the metal washer to the end of the string that is touching the windshield. Push the washer into the tennis ball through the hole you created with the screwdriver.
