In Diabolo, you try to balance a moving object between two sticks and the string that connects them. The faster you get the diabolo to spin, the more stable it is likely to stay on the rope. The fixed axle diabolo is good for beginners as it is a little easier to control. The mottled effect on the cups helps beginners recognise when the diabolo slows down and needs to be sped up. It is also slightly heavier than other medium-sized diabolos, which allows the diabolo to maintain its speed for longer, giving the player more time to learn tricks.
