Forget the batteries, and the electrical outlet. Upside Down Overpass is a fast paced, gravity-defying car and track - and the high voltage action is powered by a wind-up back and forth motion! But first, there's the anticipation of designing one of three track layouts (instructions included) and the more complex, the more loops and thrills. The Porsche BoxterÖ can go totally upside down five times in a row!

Ages 4 to 9 years.
