One-Calorie Chocolate Bender

Le Whif, a lipstick-shaped inhaler, imparts a sweet high from just a few tiny particles of chocolate. "When you inhale, the particles immediately react with your taste buds, so you get this intense taste for less than one calorie," says Harvard University biomedical engineering professor David Edwards, PhD, who worked with a team of students and a chef to develop Le Whif (which also comes in mint and raspberry).

$14 for six Whifs (each containing four to five "puffs"); LeWhif.com.
