Slides! Bloody huge, towering, twisty-turny slides! In sexy glass and steel so pretentious types who only allow themselves to have fun in the guise of "art" and "post-modern ironic comment on the politics of the playground" can have a go!

The latest in the Unilever series of Really Big Art In A Really Big Space for the Tate Modern Turbine Hall is Carsten Holler's installation of tall, twisting, glass covered slides that look like half-organic ventilation shafts growing and unfurling across the enormous Turbine Hall's empty space.

The slides are there to be looked at as spectacle, but a spectacle that the viewer can become part of as well: once the viewer enters the slide and starts to slip down the turns and coils towards the bottom, the viewer becomes the viewed... and yet remains a viewer even while in the very heart of the slide itself, maintaining an objectivity by observing the gallery space and the static ground-level viewers through the glass cover of the slide. Who is watching who? Who is the spectacle?

And... who cares? It's a big, tall, twisting slide and you can have a go on it from today until April next year. For free, with all your mates. All together now: Wheeeeeeeeeeeee!
