Using this Disney Pixar Cars glow - in - the - dark racing set is easy. First, take out the Lightning McQueen and Jackson Storm Glow Racers vehicles from the package. For daytime mode, set up the playset and simply launch the racers straight across the track. When you want to switch to nighttime mode, reconfigure the track for criss - cross stunting and watch the glow - in - the - dark feature light up. Remember, the colours and decorations on the vehicles may not be exactly the same as shown. Keep the set away from sharp objects to avoid damage. After play, store it in a dry place to maintain its condition. This set is suitable for kids aged 4 and up, so adult supervision might be needed for younger children.
