The Constant Velocity Car flips over, spins around and lights up, over and over and over again. It also comes in great bright colors with stickers, just like a dune buggy would! Fun gift for the holidays for a girl or boy who loves to watch things move, this also makes a great classroom prize for the next geography bowl. Don't worry if it runs into an object while zooming across the floor--it will flip over and start moving again!
