We're always pleased with ourselves when we can get a pen to stand on end, but artist Paul Cocksedge has really taken it to the next level.
This amazing table weighs around 1,000lb (454kg) and is perfectly designed to rest in equilibrium: one millimetre's horziontal deviance in any direction would cause the creation to topple over.
The series of ten 'poised tables', are all made from a single sheet of metal and, naturally, required a great deal of careful mathematical calculations.
The structure is currently on display at the London-based artist's first solo exhibition, 'Paul Cocksedge: Capture', at New York's Friedman Benda gallery - it runs until October 12, 2013.
