The Shake and Go Speedway is a toy racetrack for children that comes with two Shake and Go cars, an infrared start/finish sensor, start gates, and an LED lap counter. Kids can shake up the cars and watch them go. As your car makes its way around the track, you'll hear different phrases from an announcer who gives you the play-by-play. With infrared sensing, the winner will be acknowledged by the track announcer. For even more fun, add Shake and Go Offroad.
