The installation by artist Alex Chinneck is a replica of the 184-year old Market Building behind it, but has been recreated to make it look as if it is floating. The installation is called ‘Take my lightning but don’t steal my thunder’ and will be in Covent Garden’s East Piazza until the 24th October.

Why not go and take a look and see if you can work out how it is done. (we think we have)
