The makers of the Chocolate Inhaler have done themselves one better. The Le Whif Coffee Inhaler, a lipstick-sized tube that contains a "breathable coffee powder," gives you a nice caffeine fix without all that drinking and swallowing messiness. How nice?

The product: Le Whif, a puffable chocolate canister that offers the sensation of eating chocolate without the calories.

Harvard professor David Edwards wrote a graphic novel envisioning a future world where people ingested their food by smelling, or "whiffing," it. That vision begot Le Whif, the chocolate inhaler.
