TABORACEK: Professor Dartnell, who is the author of the book author of 'The Knowledge: How To Rebuild Our World From Scratch' also advises people to head to the beach, the supermarket or a golf course if an apocalypse should strike.
He says that glass is crucial to re-building and a beach offers sand as well as other raw materials such as chalk and seaweed.
What's more, basic, tools like a lathe, can be made from sand and old drinks cans.
Those heading to the average supermarket should find enough supplies to keep them alive for 55 years.
