Fill the milk jug all the way up with water and put on the cap.
Fill the large bowl about halfway with water.
Turn the milk jug upside down into the bowl of water.
With the mouth of the bottle under the water, carefully remove the cap.
Work one end of the straw up into the mouth of the bottle and hold the other end of the straw securely.
Take a deep breath and slowly blow into the straw.
Your breath will enter the milk jug and push the water out of the jug.
Once you have emptied your lungs, mark the level of water in the jug with the permanent marker.
Lift the jug from the bowl and allow the remaining water to empty out.
Now fill the jug with water up to the mark you just made.
You can now pour this water into the measuring cup to determine your lung capacity.
