Four young people compete to see who can solve the the Rubik's Cube puzzle in the fastest time.

Invented in 1974 by Hungarian architecture professor Ernó Rubik, the Rubik's Cube has become one of the biggest selling toys of all time. In 1980 4.5 million Rubik's Cube were made and sold and sales in 1981 are expected to reach about 10 million.

Paul Scattergood, brothers Brian and Fergus Griffin and Susan Green take part in a contest to see who can solve a Rubik's Cube in the fastest time.

The four competitors do not use their own Rubik's Cubes and they all start the puzzle from scratch. Everyone in the 'Late Late Show' audience also has a Rubik’s Cube so they can participate in the contest. The first person to solve the combination puzzle must shout 'finished'.

Brian Griffin completes his Rubik's Cube in one minute, winning a £30 voucher for books for his efforts. The next competitor to finish in 1 minute 20 seconds is Paul Scattergood. Susan Green finishes in 1 minute 22 seconds. Fergus Griffin completes his Cube in 1 minute 35 seconds.

Brian Griffin reveals he has written a book on how to solve the Rubik's Cube and it is for sale around the Dublin suburb of Cabinteely.

This episode of ‘The Late Late Show’ was broadcast on 3 October 1981. The presenter is Gay Byrne.
