A Hong Kong-based company has introduced what’s either the most annoying or the most brilliant eating utensil ever: a sensor-equipped fork that buzzes and lights up when you eat too fast, effectively irritating you into slowing down. The slower you eat, the less you eat, or so the theory goes. One fatal flaw: Hapifork is available in fork form only. So there’s nothing to stop you from, say, picking up a spoon and shoveling a gallon of ice cream into your mouth. Hapifork was showcased at CES last week, and it’s available on pre-order for $99. Here, Hapilabs’s Philippe Monteiro Da Rocha explains how it works.
