The Skyrail Glow in the Dark Roller Coaster from ThinkGeek is comprised of 150-pieces and lets you “build the track (as shown in the instructions) with three loops; maybe you’ll build the one where the marbles jump from one track to another.” Available now, priced at $34.99. Video after the break.

..maybe you’ll become a master fast enough to design your own crazy rides, and put the marbles through the G-force-iest ride ever. Or maybe you’ll actually let you kids play with the Skyrail Glow in the Dark Rollercoaster.
