Come along to try out an amazing bouncy scale model of Stonehenge, especially commissioned to mark the Olympics.

It will arrive on Hampstead Heath for a one day on the morning of 1 August 2012.

Created by the Turner prize-winning artist Jeremy Deller, this interactive artwork named 'Sacrilege' was first shown in Glasgow's International Festival of Visual Art in Spring 2012 and has since been touring the country. Don't miss this spectacle and get ready to release your inner childe and start bouncing!
