Rubik’s well used cube!

Fifty years old this year, the cube like many former crazes, is suddenly all the rage again!
The record for solving it is apparently only 3 seconds! The current Scottish record is 7 seconds, I think. Our grandchildren are striving to achieve their own PBs and are getting quicker by the day! Back in the day I wrote a libretto for a school operetta. Perhaps the time has come for its reprise?!
