How the lungs work

Cut the bottom off a large bottle. Fit a cork to the neck with a Y tube in it. On every of the lower limbs of the Y tie a rubber balloon or a number of small bladder.

Tie a sheet of brown paper or sheet rubber round the bottom of the jar, with a piece of String knotted by a hole and sealed with wax. Pulling this string lowers the diaphragm and air enters the neck of the Y piece causing the balloons to dilate.
