Dr Karl tackles life’s myths and absurdities in his latest offering, Great Mythconceptions. The strange facts and freaky discoveries just keep on coming in Great Mythconceptions. Dr Karl teases and tempts us by debunking (or not) common urban myths – or mythconceptions! Did man really land on the Moon? Does the soul weigh 21 grams? Did Einstein fail school? Do we really use only 10% of our brain? Did hydrogen seal the fate of the Hindenberg airship? Does a duck's quack echo? Is the Black Box black? Is a 'quantum' leap huge? Is there really a truth serum? Is a camel’s hump full of water? Can mosquitoes really infect you with the AIDS virus? And is it really written in the stars?
