Right or left - that's the question! Because in which direction the wheels turn depends entirely on the speed of the balls. And all of a sudden, physics is exciting than ever! Note: Only playable with the Kosmos Gecko Run "Starter Set" or the 'Big Box'. Those who skilfully build can assemble the two different sized wheels into a kind of gearbox. This makes surprisingly great effects possible. Together with the additional parts, this set extends the length of the track and offers an extra dose of tinkering fun. Here the ball rotates on the wheel! The quick start guide explains how the two wheels are ideally used in the marble run and you're ready to go.
