Diabolo also known as the Chinese yoyo is a skill toy born in ancient China. Today, tricks with diabolo are often part of circus performances, including those from Cirque du Soleil. What is a diabolo, exactly? The hourglass-shaped object, consisting of two attached cups, is complemented by a string and two sticks. This allows for a wide range of tricks, with diabolo being tossed, spun on the string, or balanced on the stick. You can even spin multiple diabolos at the same time!
