Professor Stephen hawking unveiled the worlds strangest clock. It cost 1 million pounds.It has no hands. It just has a grass hopper on top that gulps down a minute after it expires depicting that time once lost cannot be got back.The grasshopper or "chronophage", meaning "time eater", advances around the 4ft-wide face, each step marking a second.Its movement triggers blue flashing lights which travel across the face eventually stopping at the correct hour and minute.But the clock is only accurate once every five minutes.The Corpus Clock is wound up by an electric motor which will last for the next 25 years.It took a team of eight engineers and craftsman five years to mould the 24-carat gold-plated face.
