An Eskimo yo-yo[a] or Alaska yo-yo[b] (Central Yupik: yuuyuuk;[19]Inupiaq: igruuraak) is a traditional two-balled skill toy played and performed by the Eskimo-speaking Alaska Natives, such as Inupiat, Siberian Yupik, and Yup'ik. It resembles fur-covered bolas and yo-yo. It is regarded as one of the most simple, yet most complex, cultural artifacts/toys in the world.[8][9] The Eskimo yo-yo involves simultaneously swinging two sealskin balls suspended on caribousinew strings in opposite directions with one hand. It is popular with Alaskans and tourists alike.[10] This traditional toy is two unequal lengths of twine, joined together, with hand-made leather objects (balls, bells, hearts) at the ends of the twine.[20][c]
The object of the Eskimo yo-yo is to make the balls circle in opposite directions at the same time. Each cord is a different length to allow the balls to pass without striking one another,[16][12] and the balls are powered by centripetal force (as they rise the performer pumps down, while they fall the performer pumps up).[17] This basic trick may be referred to as the "Eskimo orbit", and the orbit may be performed vertically, horizontally, or (horizontally) above one's head.[21] Other tricks or patterns include atypical beginnings and wrapping and/or bouncing the strings around a part of one's body and then continuing with the orbit. A three-ball version of the Eskimo yo-yo also exists, and this requires all three balls to be moving at the same time.[22]
The objects at the end of the string are made in a variety of shapes, ranging from seals, ptarmigan feet and dolls, to miniature mukluks and simple balls.[10][12] The handle may be wood, bone, or ivory,[13] as well as baleen. Many are plainly decorated; others display elaborate decorations, fine beadwork, and intricate details.[10] The Eskimo yo-yo is bola, toy, and art form all rolled into one. One of their most popular forms of the Alaska Native art are yo-yos. Also, this is a popular tourist art found in gift shops across Alaska.[10] See: Indian Arts and Crafts Act of 1990. Much like the spinning top (e.g. Maxwell's top), the yo-yo may also be used to demonstrate visual properties such as optical rotation[23] and circular dichroism.[24]
Though the early history of the Eskimo yo-yo is not recorded, Eskimos maintain that this game originated as an important and widely used hunting tool made simply with sinew and bones, the bola.[10][15][18] It possibly evolved on St. Lawrence Island from the similarly constructed sinew and rock bolas used in bird hunting.[11]
