A very impressive slide at in the Turbine Hall at Tate Modern. We rode from the fifth floor. Strange sounds escaped from me without my bidding.

Apparently the fourth floor slide is faster - with a much longer queue - but I went after Mark Kermode (he refused the bump cap offered; mine fell off half way down - I suspect his greasy 'duck's arse' hairstyle lubricated the slide ahead of my turn) and it was a longer ride so I think we made a good choice.
