Yep, it's just like Stonehenge but in bouncy castle form! Bouncy Stonehenge, or Sacrilege to give it it's proper name, is currently in London for the London 2012 Festival, and will be travelling around the rest of the country until the last day of the Paralympics on 9th September.
Once you've had your Stonehenge bounce, you can print yourself off a certificate of participation from the website, and even an emergency beard to wear, if such a thing is necessary.
If you're hoping to visit, the remaining tour dates are below:
1 August – Hampstead Heath, London
31 July - Ravenscourt Park, London
