Diabolo

The diabolo (/diːˈæbəloʊ/ dee-AB-ə-loh; commonly misspelled diablo) is a juggling or circus prop consisting of an axle (British English: bobbin) and two cups (hourglass/egg timer shaped) or discs derived from the Chinese yo-yo. This object is spun using a string attached to two hand sticks ("batons" or "wands"). A large variety, possibly, "hundreds," of tricks are possible with the diabolo, including tosses, and various types of interaction with the sticks, string, and various parts of the user's body. Multiple diabolos can be spun on a single string.

Like the Western yo-yo, it maintains its spinning motion through a rotating effect based on conservation of angular momentum.

Diabolos evolved from the Chinese yo-yo, which was originally standardized in the 12th century. Chinese yo-yos have a longer axle with discs on either end, while the diabolo has a very short axle and larger, round cups on either end. Diabolos are made of different materials and come in different sizes and weights.

There are many names in the Chinese language for the Chinese yo-yo:

The first mention of a diabolo in the West was made by a missionary, Father Amiot, in Beijing in 1792 during Lord Macartney's ambassadorship, after which examples where brought to Europe, as was the sheng (eventually adapted to the harmonica and accordion).
