A Bee's Powerful Nose
Like Pavlov's dogs, this honeybee has been trained to extend its tongue for food whenever it is stimulated with a certain scent. The bee was fixed in a tiny harness with tape and then stimulated with an odor. Given its superb sense of smell, the bee quickly learned to associate the smell with food.
