Straight off Willy Wonka's production line comes the Chocolate Calculator. Wrapped in its snazzy purple packaging and silver foil you be drooling at the mouth as soon as you get your hands on it. Then as you tear off the foil you are even hit by the sweet aroma of chocolaty goodness. Finally as you put it in your mouth you can savour the taste of........plastic! That's because no matter how good it looks or tastes, it's a calculator! At least its 0 calories.
