Goliath Games: YO-YO Yofinity Assortment
Kids arcade toy
YOYO is a toy in the form of a bobbin-sinker suspended on a string.
The weight, lowered on a string held by the unsecured end, unfolds it, making it rotate. After the string is fully unwound, the weight retains the angular momentum of the rotating motion and while winding the string, it goes up. To play with yo-yo, you need to put your finger in the loop of the string and carefully wrap the string on the axis,
then lower the yo-yo and gently jerk it up at the right moment.
