Six-year-old breaks Rubik’s Cube world record twice in three days
China’s Lian Yunzhi averaged 4.27 seconds across five solves, breaking the women’s 3x3x3 Rubik’s Cube record she had set just three days earlier. Her 4.27-second mark made her the only female speedcuber in history to ever record an official average time under 4.5 seconds.
