Construct exciting glow-in-the-dark marble runs using transparent coloured pieces and glow-in-the-dark marbles. Watch the marbles as they travel down the see-through chutes and tubes and swirl around the vortex. Turn off the lights, place the marbles in the glow-in-the-dark starter tops and the glowing marbles look as if they are flying through the air as the marble run has dissappeared in the dark!
