Steven Purugganan Speed Stacking Wizard

Have you tried speed stacking? It’s that set of 3, 6, 3 cups which you stack up and down as fast as you can. There’s a certain sequence that you have to follow, where you build a stack of 3 cups, 6 cups, and even 10 cups. You end the sequence by bringing the cups back to the original 3-6-3 position.

Steven Purugganan is a veritable speed stacking champion, who can do the complete cycle in 6.21 seconds. Watch… try not to blink:
