Bubbles Rising in Water

[JointVentureDive]

Hi Steve,
This is very a very interesting article.  However, as my life story can attest, BLOOD IS THICKER THEN WATER,  LOL..  and if this is true in physics and hemotology, can we use the same information across the board in any liquid?  just food for thought, I bet John J. or Bob have a good answer for this.

I would not like to necessary rely on my ability to follow that smallest bubble up, plus what if the bubble stopped, would I stay down.  Just kiddin on that one.

Thanks, Steve, I love all this stuff.
