Brilliant! The architects behind “The World’s Greatest Shelby Slot Car Racetrack” have engineered an ingenious way of looping 63 feet of track by creating raised tracks which loop over and around each other. Unfortunately, we can’t figure out who exactly built this track for Restoration Hardware.

But may we suggest that instead of opening the box you carry it around with you always, hoping to bump into old Carroll and get him to sign it? Order yours from Restoration Hardware for $249. It’s on backorder but they say orders ship December 1st. Just in time for it to spark and catch your dried-out Christmas tree on fire.
