Lung/Diaphragm Demo

SKU #DIA-100
Availability: In Stock
Qty.
Great hands-on demo of how our lungs work.

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.

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.
