Task 2: Measure the volume of the lungs by so-called spirometer made from a PET bottle.
Make a 5 litre graduated cylinder from the jerry can. Fill the spirometer with water, close it and place it in the washbasin so that the neck is under water. Uncoil the spirometer and insert the hose into the neck (Fig. 5). By exhaling the air into the tubing, you will find the volume of your lungs.
