Without a pump, how do some animals inflate their lungs? Pull down on the rubber diaphragm and the balloon lungs inflate; release and they deflate. Large enough for small groups to see, small enough to remain as an interesting item on your desk during the year! Approx. 8.8 cm (3.5") tall. Colors may vary.
