The Hot Wheels® Action Spiral Speed Crash™ Track Set delivers big-time thrills with a 29-inch-tall track, three crash zones and a motorized booster that keeps the car moving. Kids can drive the included Hot Wheels® vehicle up to the booster and watch it continuously whip down the spiral. To increase the challenge, they can add additional cars until there's an inevitable wipe-out in one of the crash zones. They can store up to 6 cars atop the battery box and booster.
