IT IS the UK’s biggest science centre, it has welcomed schoolchildren and celebrities, politicians and pensioners, educators and experts from all over the world through its doors – and this week, it celebrates its 21st birthday.

Her Majesty The Queen officially opened Glasgow Science Centre on July 5, 2001, and since then it has become a much-loved part of the city.

Exhibitions and displays have come and gone (who remembers Alice in Wonderland?), others have been updated and refreshed (the sand table, the vortex cannon, and the distorting mirrors) by the in-house team of engineers who keep on top of running repairs, and the science communicators have always been on hand to help explain what’s going on.

The centre has been used for everything from fashion awards ceremonies to party political conferences, it has been visited by Royals (the Duchess of Wessex opened the Wonderland exhibition in 2006), politicians (Benazir Bhutto, Gordon Brown, amongst others) and celebrities (Anneka Rice, Heather ‘The Weather’ Reid, Liz Lochhead, Chris Hadfield….)

There have been ground-breaking exhibits (the live autopsy table as part of Bodyworks caused a stir) and sensational science demonstrations.
