Watch as the Hyperspeed Hangtime Roller Coaster Building Set from K'NEX uses its inverted blaster motor technology to send cars flying through twists and turns while hanging upside down. Standing over 2 1/2" tall when finished and nearly 4" wide, build this set with over 620 K'NEX parts and pieces including rods, connectors, and track.
