Rounding chocolate to boost sweetness

In 2011, Coca-Cola introduced a white version of their Coca-Cola can. The drink inside was identical to original Coca-Cola, but customers drinking from this white can hated the taste. 

The white can made buyers think the Cola tasted worse. 

To explain why, I need to delve into the science of sensehacking. With Professor Adrian North, I’ll explain why tennis players grunt loudly, why cars smell different when new, how a tablecloth alters our taste, and that music changes what you buy.
