Choosing the Time and the Victim

  1. Don’t try this prank on a someone who is likely to totally lose it and never do it to someone who is learning to drive or uncertain about driving. Choose that good buddy who will totally enjoy the prank.
    • Consider creating the rainbow to cheer up a friend or someone who has been sad or depressed. It might be a fun, sunny way to let that person know that everything will be okay.
  2. It's probably best to do this on a day when you know it might rain (so that the windshield wipers will be necessary). However, avoid days where the rain is bucketing down; it's a fine balancing act to get a day with light rain!

Setting Up the Rainbow Prank

  1. Distract them somehow until you're ready.
    • Don’t allow for too much time to pass between when you apply the color and when you want the rainbow to appear, as the paint may dry over time.

    Place first color toward the end of the wiper blade (toward the outside) and then work your way toward the middle.
    • Create a 1” to 2” (2.5-5cm) line with each color. You want enough color to create the rainbow, but without being overly suspicious or within the driver’s sight line.
    • For the sake of safety, only add the colors to the passenger side window, so that the driver can still see.

    You want the rainbow colors to blend once the windshield wiper has been activated, so the colors should be placed close together.

    That way you can see the driver/your friend’s reaction immediately (which presumably, is the whole point).
    • Alternatively, you could hide so your intended driver/target has no idea you are the one who placed the color on the windshield. But where's the fun in that?!

    Be available right away to tell your friend the paint is washable and then offer to remove it if they don't see the humor in the prank.

      Tips

      • Create the rainbow on a random Monday morning on the car of someone you love; it might be a fun way to chase the Monday blues away.
      • This project works best with a single blade windshield wiper.
      • Confirm that the paint you apply to the windshield is easily washable in the event paint dribbles on the car exterior.

      Warnings

      • This can be a distraction. Don't do this if you have any doubts that the driver is insecure about driving and don't do it when the person is likely to be driving in heavy traffic or difficult weather conditions.
      • Some people will inevitably get very upset when they see paint on their car. You'll need to do some quick explaining and reassuring.
      • Be aware that this could damage the paintwork of the car that gets pranked, as even acrylic paint contains a solvent that can damage poly acrylic automotive finishes. Or, dried paint could cause the wiper motor gears to seize or a blade could rip off.

      Things You'll Need

      • Washable acrylic paint in rainbow colors (red, orange, yellow, green, blue and purple); paint inside tubes is the best way to apply the color to the windshield. You can also use broken down crayons instead.

      • Soft microfiber cloth and car wash soap for quick removal of the paint
