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.

Pressing the diaphragm upwards has the opposite effect.
