#82: Tomorrow's World Christmas Quiz, 1987

Every year between 1986 and 1992 the team would kick off their tight shoes for a Christmas Quiz with an eclectic guest list and a chance to have fun with science. This year Bob Symes, who died in January, gets to stay at home for his parts while ion the studio unlikely inventions are put to the test to determine what they're actually for, in the company of Moira Stewart, Rod Hull and Emu, Keith Chegwin, George Takei and Patrick Moore.
