The Hot Wheels Massive Loop Mayhem track set will definitely make kids loopy from the thrilling excitement. This epic track includes a huge 28-inch tall loop that's designed for multi-car play -- vehicles whip around the loop and avoid nail-biting near-misses with each other. Kids send the first car into action using the slam launcher, then add more and more cars until there's the inevitable crash (additional cars sold separately). The challenge lies in how many cars can run at once -- it's a trick of timing and skill. The track comes with one 1:64 scale Hot Wheels vehicle to get the action started. Colours and decorations may vary.
