I have subscribed to way too many science blogs. I’d drop some them but then I’d miss out so much good science. Like this experiment on a bottomless bowl of soup.
Dr. Wansink is particularly proud of his bottomless soup bowl, which he and some undergraduates devised with insulated tubing, plastic dinnerware and a pot of hot tomato soup rigged to keep the bowl about half full. The idea was to test which would make people stop eating: visual cues, or a feeling of fullness.
People using normal soup bowls ate about nine ounces. The typical bottomless soup bowl diner ate 15 ounces. Some of those ate more than a quart, and didn’t stop until the 20-minute experiment was over.
