Looking like the best slides I've seen since I was a kid living in Germany (the Germans have the best slides) these 'sculptures' by Carsten Höller are the latest work to fill the Turbine hall at the Tate Modern. The best news is that the 'Please do not touch the artwork signs' will not be in attendance - you can actually slide on them, with a free ticket. Get there before some kid does himself an injury and the exhibit is closed on health and safety grounds.
