I never saw anybody say this, and I couldn't see air cells when I looked for them. I figured it out.
Turn the egg so the light is shining up sideways past the air cell, then when you turn the egg just right, you can see it clearly.
I was shining the light in through the small end of the egg, then through the big end, and couldn't see it.
