Science has performed some unusual experiments over the years. For instance, Dr Pavlov made news some years ago by ringing a bell to call dogs to dinner - and soon he noticed that the dogs developed a curious reflex after being exposed to the ringing bell. Although, this comes as no surprise to the parents of any youngster who has been exposed to the bell of the ice-cream man! This is the story of ice-cream. It’s been a long road from frozen water to a super special chocolate sundae and Nero, Marco Polo, George Washington, Dolly Madison, Nancy Johnson and William Young have all had a hand in it over the years, helping bring to perfection one of America’s and the worlds greatest foods and delicacies.
