'Your Blind Passenger'

'Your Blind Passenger' from Olafur Eliasson's exhibition "In Real Life" at Tate Modern is a 39-metre long passageway filled with fog. You can see about 1.5 metres in front of you, and the fog changes colour as you go through. It's made from water-soluble fog fluid containing non-toxic polyols, so an interesting experience that is quite safe.
