The Zink Brothers sometimes yo-yo for five hours a day. But Joel and Ryan aren't loopy--they're yo-yo pros. Joel, 14, is the world, international and U.S. national yo-yo champ. Ryan, 11, won the advanced category at last year's international and world competitions.
The boys occasionally compete in the same category. Still, says Ryan, "we help each other" learn new tricks. Cool, yo.
