The coolest pull-back engine racer ever - Marble Racers Light-Up Pull-Back Racing Cars! Marble Racers utilize Motion Activated LED lights to bring the coolest blink and flicker light action to your child's racing car playtime! Marble Racers cars feature an interior marble with the motion-activated LED light inside - give it a shake and the red, blue, green and purple lights flicker and flash as the marble spins! Then pull the car back along any hard, flat surface and let go to see your car fly across the room! See how straight you can point the car so it will travel the longest distance or set up your own ramp for daredevil stunts. Add a second car so that you can race your friends, too! Assorted colours - each sold separately. 3+ years.
