If you think a device that lets you inhale chocolate is strange, then here’s some more strangeness for you. The concept of “inhaling food” is catching on, particularly with diners in Europe, and now one Canadian restaurant serves gases that “taste” like food, but without those pesky carbs, fats or calories.

This bit of kitchen alchemy comes courtesy of a device called the Le Whaf, created by French scientist and Harvard professor David Edwards, who was inspired by the aforementioned inhalable chocolate device. The Le Whaf is a large glass carafe with an ultrasound device at the bottom. When a liquid is introduced — like a consommé — the ultrasound waves agitates the liquid hard and fast enough it turns the liquid into gas. It’s this gas that diners are encouraged to inhale through a straw.
