A German skydiver solved a Rubik's Cube(魔方) while sitting in a rubber dinghy - as it plunged to earth from 4000m. Ludwig Fichte, 29, was filmed completing the classic puzzle while falling 1800m in 31.5 seconds. He then deployed his parachute and floated to the ground.

Fichte, from Dresden, said: "Solving the Rubik's Cube in freefall has been done before by three people, as far as I know. But I am the first to do it in a rubber boat. I want to skydive again - maybe to compete with another speedcuber sitting in the boat."

Reminds me of...

my skydive from 12,000 ft in NZ - the free-fall is a duration of the coolest 40+ seconds, but, kid you not, I can't even think straight! Let alone solving a bloody puzzle...

By the way,...

The current world record for single time on a 3×3×3 Rubik's Cube was set by Erik Akkersdijk  in 2008, who had a best time of 7.08 seconds at the Czech Open 2008. The world record average solve is currently held by Feliks Zemdegs; which is 8.52 seconds at the New Zealand Championships 2010.

Many general solutions for the Rubik's Cube have been discovered independently. The most popular method was developed by David Singmaster and published in the book Notes on Rubik's "Magic Cube"  in 1981. This solution involves solving the Cube layer by layer, in which one layer (designated the top) is solved first, followed by the middle layer, and then the final and bottom layer. After practice, solving the Cube layer by layer can be done in under one minute. Other general solutions include "corners first" methods or combinations of several other methods. In 1982, David Singmaster and Alexander Frey hypothesised that the number of moves needed to solve the Rubik's Cube, given an ideal algorithm, might be in "the low twenties". In 2007, Daniel Kunkle and Gene Cooperman used computer search methods to demonstrate that any 3×3×3 Rubik's Cube configuration can be solved in 26 moves or less. In 2008, Tomas Rokicki lowered that number to 22 moves, and in July 2010, a team of researchers including Rokicki, working with Google, proved the so-called "God's number" to be 20.
