Techniquest at 40

Adam Walton celebrates the 40th anniversary of Techniquest in Cardiff, a science discovery centre that makes exploring STEM both fun and educational.

Wendy Beetlestone remembers her father John Beetlestone who founded Techniquest.

Colin Johnson, Harry White and Wendy Sadler reminisce about the earlier years of the centre, while Sue Wardle and Dan O’Toole look to the future.

And we hear about the return of classic exhibitions "Mirror Maze" and "Head on a Plate."
