Just over 300 years ago, an apple rudely interrupted Isaac Newton's midday repose, in the first recorded instance of a thing dropping on somebody's head. After lambasting the blasted Cox, the Lucasian polymath got to the core of the problem, and promptly invented gravity. Everything on Earth has got down with his laws ever since.
Well, nearly everything. Rules are made to be broken, especially abstract scientific ones inspired by falling fruit. For all we can generally feel quite assured that a cuppa isn't going to drift skywards the moment we put it down on our desk, there are some places on Earth where this seemingly doesn't apply.
These are the recalcitrant spots on our planet where gravity is absolutely nowhere to be found - and we're not talking a branch of HMV which has sold out of Sandra Bullocks movies. Whether kitschy tourist curios in American lay-bys, undulating hills housing fields of magnets, or most of bloody Canada, it's recommended you strap your hat on - and your gullibility - when you visit these Newtonian nightmares. What goes up doesn't always come down.
