Art gallery visitors plunged into darkness

The latest art installation at the Tate Modern is a a blacked out steel chamber where visitors can't see anything.

It is the work of Polish artist Miroslaw Balka who says entering the darkness could evoke a variety of responses in visitors, from fear to a bizarre feeling of comfort.  

Visitors walk up a ramp into the 30 metres long, 10m wide and 13m high box which has been painted black before disappearing into it.

Once inside they can see nothing and are left waving their arms out in front of them so they don't bump into other vision challenged art-lovers.

Help is on hand should anyone get too freaked out by the darkness… Tate Modern staff will be patrolling inside with torches.
