Holy crap! 40 years???
Easy way to solve a rubic's cube
Find the red center block and pry it out.
Undo the screw and disassemble the stupid thing
Reassemble it with all the colors matching, replace the screw and replace the red center block.
As a species, we are tool users for a reason.
If you have some smart assed 7 year old bragging about how fast he can solve a Rubic's cube?
With a very thin knife, carefully peel off two different color labels and switch their positions.
Hand it to the smart ass and watch the fun start.
