Description
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.Video

Adorable!

Truthfully told, I wasn't sure how the quality would be. Well, let me tell you it is great! The clear plastic cup is thick, the pull diaphram is sturdy, and there is an extra set of balloons in the pack just in case. It will be a great addition to our human biology lab.

I used this as a raffle item, because we studied the lungs in class.
