Fun: Speed Stacking

Wow is all I could say when I saw this video. Basically Emily Fox is a 15/16 year old student who can “speed stack” and unstack cups in the format 3-6-3 (3 cups on either side a 6 cup pyramid) in 2.72 seconds and can do a “cycle stack” (of 3-6-3 followed by a 1-10-1 pyramid followed by a 3-6-3 “down stack”) in 7.43 seconds (that’s a world record).

Just look at her hands go! I’ve watched the video and worked out that she touched each of the 12 cups 6 times – that means she was placing a cup every tenth of a second. Ok, she used both hands – but that still means changing cups every one fifth of a second.
