Gung-Ho! London

It's time to do some serious kidulting because the world's biggest inflatable obstacle course is coming to London. The 5 kilometre-long circuit consists of no less than 10 adult-sized blow-up hurdles. Not only will you be able to whizz down a five-storey-high, 200 foot-long slide, there'll also be a giant blow-up ball pit to fight your way through. Tickets cost£32 until Monday 16 January, when they go up in price.
