The spiral 'elevator' lifts the marbles up to the top of the rail, and gravity takes care of the rest. It’s entertaining, and a great lesson in physics that also has a glow in the dark rail. If you don’t get the angles of the track right, the marbles won’t make the journey! Hours of entertainment, and virtually unlimited track possibilities! Once you get it right though, they’ll keep going around and around until you stop them (usually to make changes to the track)! Supplied with loads of pieces to make up to 10m track.
