    I see that you are not detecting some bubbles AND that you need to block ambient light somewhat.
    Why not put a couple drops of food coloring into the water trap. Say dark blue? This way the transmitivity will be very different between a bubble and no bubble. Bet this also makes blocking the ambient light unnecessary.

No public wish lists :(
