Yin Yang Glass of Water Half Full and Half Empty

[Raspberry Ripple]

Hi,
I am trying to make a fake image that shows a glass of water,
to simultanously illustrate two concepts :
1. glass half full (or half empty) (optimist/pessimist)
2. yin yang
in the sense that
- a bubble of emptiness is located inside the water and
- a bubble of water is floating in the emptiness.

My latest attempt is not very convincing http://tinyurl.com/m6xaof9.
(I am not an artist.)
Would anyone like to try to do a better job ?
Just for the fun, and for free ?
I mean if it's going to take you more than 15 minutes, don't bother.
And post your result somewhere and let me know.
Is that OK ?

Thanks in advance,
Raspberry Ripple

You could photograph the glass, see an old photo of mine, attached.
No bubbles, but it is partially full.

Thanks Joelle,
but at home I already have several glasses,no shortage of water, and a camera.
My real difficulty would be the bubbles.
Thanks anyway.
