In Joseph Wright’s An Experiment on a Bird in the Air Pump: 1) describe the experiment, 2) what kind of bird did they use? why? 3) What was the result of the experiment?
He put a bird into a glass container that was connected to a pump. The demonstrator then pumped out the air in order to show the effect on the bird, which is a white cockatoo. Since in reality such a bird is valuable, it was probably chosen for dramatic effect. The bird fell to the bottom of the container.
