This innovative marble run uses a strong yet removable adhesive material to stick to smooth, vertical surfaces. Design and build your own epic marble runs without the height limitations of traditional marble runs, which must be built up from a horizontal surface. Place the flexible tracks and stunt elements where you want them, then take some test runs with the metal marbles. You can move parts and change your setup with ease to achieve the perfect run. Through hands-on experimentation, create your own spectacular marble runs and observe physics phenomena firsthand. The nano-adhesive pads adhere to smooth surfaces such as glass, wood, tile, and more and can be repositioned easily without leaving any residue or damaging the surfaces. The durable materials allow for long-term enjoyment, and the tracks are made from renewable raw materials. A 16-page, illustrated manual guides you through setting up your first runs and teaches you how all the different elements work.
