A specific marble run toy set that includes glow-in-the-dark marbles and various pieces like spirals and a loop-de-loop. Despite its name, it does not operate in zero gravity; it's a standard marble run that relies on gravity to move the marbles down the track, which is constructed with different heights to create a visually interesting path with a starting point that must be higher than the end point
