Can you redesign a chocolate bar?

Found this very interesting article:

David Sherwin, author of the upcoming book Creative Workshop, is sharing some of the design challenges from his book on his blog. Some of these are really fun and provocative.

This week’s challenge:

Choose a product you use as part of your day-to-day life—food, drink, paper products, etc.—and  redesign or repackage it so that consumers will want to use less of it.

How can you use your design skills to make more out of less and encourage people to use that reduced quantity in a more mindful manner?
