Thanks to my speed-loving toddler I’ve gone down more slides in the past few months than in the rest of my life (have I mentioned that I’m scared of heights?). He would surely want to visit the Tate Modern’s astounding slide installation by Carsten Höller. Unfortunately he’s too short to go on most of them. There are five slides installed in spacious Turbine Hall which previously held the generators of the power station that was renovated into the museum. The biggest slide is about 182 feet long and the sliders, using canvas sacks, reach speeds of 30mph. Höller is Belgian and has a doctorate in biology. All his works have a touch of whimsy.
