With Quercetti Mini Rail Roller Coaster, you can build super long glow in the dark marble runs, spanning nearly 27 feet! These spectacular aerial pathways will be the main attraction of your room. The 150 pieces can be assembled in many different ways: you can follow the enclosed instructions, or use your imagination to create your own layouts. With Quercetti Mini Rail Roller Coaster marbles, they don't travel only downward at constant speed like in old-fashion marble runs, but can accelerate down steep slopes then climb uphill until almost reaching a stop, roll quietly along flat plateaus, and plunge down at full speed.

Quercetti Mini Rail Roller Coaster is designed in such a way that most types of marbles, in various sizes, can run along its tracks. Two types are included in the box. Each marble type will run at different speed and will allow you to observe, experiment and discover the world of physics forces and to understand its fundamental principles!

Includes 150 pieces and instructions, and it really glows in the dark!

Assembled track measures approximately 29.5' long.
