Optical Trick

Shops, restaurants, commercials… Everything keeps telling us “Eat! Eat more and more often!” We obey and start eating even when we have no appetite.

DANGER #3 optical trick

Long narrow glasses seem to be roomier than short wide ones of the same volume. Participants of the experience drank 20% more juice from small glasses though they had a feeling that they had drunk less. It has something to do with the human eye: at first it perceives the height of the object, and only then its width. That’s why the volume of a short wide glass seems to us to be smaller intuitively.

How to avoid this danger? Drink caloric juices from tall narrow glasses and you’ll drink less.
