Simple but effective way of showing how smoking damages the lungs.  Comparing the air sacs of the lungs to bubble wrap, this 3D model of 2 lungs shows the bronchial air passages into two bubble wrap lungs.  The smokefree lung is pink and healthy with all the air sacs intact.  The smoker lung is black from tar, has holes burned into the air sacs to represent emphysema and has cancerous growths and a pool of phlegm.   The background chart explains the differences between the smokefree and smoker lungs and this is explored further with a handout called Love your lungs.  The box is covered with an acrylic cover and ready to hang.
